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.

L.C.M * H.C.F=FIRSTNUMEBR * SECONDNUMBER

Co prime means not get co-prime (1, 3).

Simple method:
LCM=product of co primes/HCF
=>4107/37=111
LCM=product of co primes/HCF
=>4107/37=111

37a*37b=4107
1369ab=4107
ab=4107/1369
ab=3
1369ab=4107
ab=4107/1369
ab=3
