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.

As 37 is the HCF of these numbers. So, we can take the smaller number is 37 and greater is 37x.
A.C, 37*37x=4107,
or, x= 4107÷(37*37),
or, x =3,
Now, the greatest number is 37*3=111 (Ans).

x*y = 4107.
Hcf of two nums is 37. So these two nums are divisible by 37.
37x*37y = 4107.
37(x*y) = 4107.
x*y = 4107/37 = 111.
Hcf of two nums is 37. So these two nums are divisible by 37.
37x*37y = 4107.
37(x*y) = 4107.
x*y = 4107/37 = 111.

Hcf x lcm = Product .
37 x X = 4107.
X = 4107/37 = 111 answer.
37 x X = 4107.
X = 4107/37 = 111 answer.

When we find the LCM as 111, why does it mean that one of the number is 111 and the other is 37. They are just factors and multiples. Please anyone explain.

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