The product of two numbers is 4107. If the H.C.F. of these numbers is 37, then the greater number is:
101
107
111
185
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.

Can LCM always be the greatest no.?

Thanks anand

Best method by verification.

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.

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

Thanks Pannu.

Anand said:   1 decade ago
Simply multiply the value 37*111=4107

Jyoti said:   1 decade ago
Simply divide the product with H.C.F
i.e 4107/37=111

Easy way to get ans:divide the product with H.C.F

-->4107/37=111;
