The product of two numbers is 4107. If the H.C.F. of these numbers is 37, then the greater number is:
Answer: Option
Explanation:
Let the numbers be 37a and 37b.
Then, 37a x 37b = 4107
ab = 3.
Now, co-primes with product 3 are (1, 3).
So, the required numbers are (37 x 1, 37 x 3) i.e., (37, 111).
Greater number = 111.

Simply as we know:
LCM x HCF = product of co-prime or a x b.
Given that,
Product of two nos = 4107
HCF = 37
LCM = ?
Finally we can put the value on above formula,
LCM*HCF = product.
LCM = 4107/37.
LCM = 111 Answer.

Best method by verification.
Divide 4107 by 37 we get 111.
Divide 4107 by 37 we get 111.

Best method is to use the co primes as it in the given explanation.
4107/37=111, which is not the correct solution.
4107/37=111, which is not the correct solution.

This will work on co-primes. If two numbers are not coprimes then how should we find out ?

Thanks Pannu.

Simply multiply the value 37*111=4107

Simply divide the product with H.C.F
i.e 4107/37=111
i.e 4107/37=111

Easy way to get ans:divide the product with H.C.F
-->4107/37=111;
-->4107/37=111;

L.C.M * H.C.F=FIRSTNUMEBR * SECONDNUMBER
IF THEY ARE COPRIMES
IF THEY ARE COPRIMES

But how we will know 37 is the H.C.F first only.
