Question

If the HCF and LCM of two numbers are 7 and 245, respectively, then their product is:

A.

1517

B.

1175

C.

1751

D.

1715

Correct option is D

Given:
H.C.F and L.C.M are 7 and 245 respectively
Formula Used:
L.C.M × H.C.F = Product of two numbers
Solution:
Here, we have H.C.F = 7 and L.C.M = 245
So, product of two numbers = HC.F × L.C.M
=> 7 × 245 = 1715
Hence, the required product is 1715.
