    Mohammed

    Guys, does anyone know the answer?

    get if the hcf of two numbers is 9, then which of the following can never be their lcm? from screen.

    The HCF of two numbers is 9. Which one can’t be their LCM?a)24b)36c)54d)48Correct answer is option 'D'. Can you explain this answer?

    H.C.F of two numbers is the highest factor present in both the numbers.So we can say, if the HCF of two numbers is 9 then the two numbers can be 9x and9y where x andy are co-prime.The LCM of these two numbers = product of these two numbers.So, LCM of 9x and 9y = 9xy (Only one 9 in the LCM because it is a common factor of both the numbers).Hence, we can conclude that the LCM must be an integral multiple of 9 as x and y are integers. From the options given only 48is the number which is not an integral multiple of 9. So it can never be the LCM.

    The HCF of two numbers is 9. Which one can’t be their LCM?a)24b)36c)54d)48Correct answer is option 'D'. Can you explain this answer?

    H.C.F of two numbers is the highest factor present in both the numbers.

    So we can say, if the HCF of two numbers is 9 then the two numbers can be 9x and 9y where x and y are co-prime.

    The LCM of these two numbers = product of these two numbers.

    So, LCM of 9x and 9y = 9xy (Only one 9 in the LCM because it is a common factor of both the numbers).

    Hence, we can conclude that the LCM must be an integral multiple of 9 as x and y are integers.

    From the options given only 48 is the number which is not an integral multiple of 9. So it can never be the LCM.

    H.C.F of two numbers is the highest factor present in both the numbers.

    So we can say, if the HCF of two numbers is 9 then the two numbers can be 9x & 9y where x & y are co-prime.

    The LCM of these two numbers = product of these two numbers

    [Because co-prime numbers don’t have any common factors other than 1]

    So, LCM of 9x & 9y = 9xy [Only one 9 in the LCM because it’s a common factor of both the numbers]

    ∴We can conclude that the LCM must be an integral multiple of 9 as x & y are integers.

    From the options given only 60 is the number which is not an integral multiple of 9. So it can never be the LCM.

    If the HCF of two numbers is 9, what is their LCM?

    Answer (1 of 3): That depends on the numbers. They could be 9 and 27, in which case the LCM is 27. They could be 36 and 45, in which case the LCM is 180. In general, if the HCF of two numbers is 9, then that means they must be divisible by 9, so let’s call the numbers 9*a and 9*b, where a and ...

    We know that: LCM(a,b)= ab HCF(a,b) LCM(a,b)=abHCF(a,b)

    unfortunately, you've only supplied one variable, so there isn't a unique answer.

    For example, HCF(9,18)=9. HCF(9,18)=9. In this case, LCM(9,18)= 18×9 9 =18. LCM(9,18)=18×99=18.

    But, this isn't a unique answer.

    That depends on the numbers.

    They could be 9 and 27, in which case the LCM is 27.

    They could be 36 and 45, in which case the LCM is 180.

    In general, if the HCF of two numbers is 9, then that means they must be divisible by 9, so let’s call the numbers 9*a and 9*b, where a and b are both integers (so 1, 2, 3), except they can’t share any prime factors, since otherwise the LCM wouldn’t be 9.

    For 9 and 27, a=1 and b=3. For 36 and 45, a=4 and b=5.

    The LCM is 9*a*b

    (Note that a and b are interchangeable.)

    If you give only HCF then the LCM will not be unique.

    For example, 9 and 18 have HCF 9 and their LCM is 18

    But if you take the numbers 9 and 27 their HCF is also 9, but their LCM is 27 !

    We can give many more examples like this !

    Two numbers have an LCM of 20 and an HCF of 4. What are they?

    Let 4a & 4b be the two numbers where a & b are co-primes.

    Now LCM x HCF = Product of numbers

    => 20 x 4 = 16ab => ab = 5

    The only possible integer values of a & b is a=1 & b= 5 or a= 5 & b = 1

    So, the required numbers are 4 and 20.

    What two numbers have the LCM of 24 and the HCF of 2?

    Least common multiple (LCM)…

    First see all the divisors of 24: 2, 3, 4, 6, 8, 12, 24

    The possible pair form that are (order is irrelevant):

    2, 3 (LCM = 6) 2, 4 (LCM = 4) 2, 6 (LCM = 6) 2, 8 (LCM = 8) 2, 12 (LCM = 12) 2, 24 (LCM = 24) 3, 4 (LCM = 12) 3, 6 (LCM = 6) 3, 8 (LCM = 24) 3, 12 (LCM = 12) 3, 24 (LCM = 24) 4, 6 (LCM = 12) 4, 8 (LCM = 8) 4, 12 (LCM = 12) 4, 24 (LCM = 24) 6, 8 (LCM = 24) 6, 12 (LCM = 12) 6, 24 (LCM = 24) 8, 12 (LCM = 24) 8, 24 (LCM = 24) 12, 24 (LCM = 24)

    The possible answers are in bold…

    Greatest common divisor (GCD === HCF)

    2, 24 (GCD = 2) 3, 8 (GCD = 1) 3, 24 (GCD = 3) 4, 24 (GCD = 4) 6, 8 (GCD = 2
