Which pairs of integers A and B have greatest common divisor 18 and least common multiple 540?

Answer 1

Oh, dude, the pairs of integers A and B that have a greatest common divisor of 18 and a least common multiple of 540 are like (18, 540) and (-18, -540). It's like finding a needle in a haystack, but hey, that's math for you. So yeah, those pairs fit the bill.

Answer 2

The greatest common divisor (GCD) of two integers A and B is the largest positive integer that divides both A and B. The least common multiple (LCM) of two integers A and B is the smallest positive integer that is a multiple of both A and B. In this case, the GCD is 18 and the LCM is 540. To find the pairs of integers A and B that satisfy these conditions, we can use the formula GCD(A, B) * LCM(A, B) = A * B. Therefore, the pairs of integers A and B that have a GCD of 18 and an LCM of 540 are (18, 540) and (-18, -540).

Answer 3

There are 4 pairs:

(18, 540), (36, 270), (54, 180) and (90, 108).

Answer 4

(18,540)(36,270)(54,180)(90,108)
