Question

If x and y are positive integers, what is the value of xy ? (1) The greatest common factor of x and y is 10. (2) The least common multiple of x and y is 180.

Answer 1

The value of xy = 1800

Explanation:

The product of x and y can be found by using the formula,

Greatest common factor of x and y × least common multiple of x and y

That is,

GCD of x & y multiplied by LCM of x & y we will get xy.

xy = 10 × 180 = 1800

Thus we can conclude the value of xy = 1800
