Question

The L.C.M of two numbers x and y is 1296 and their H.C.F. is 36. How many ordered pairs of form can be formed?

Answer 1

Answer:

LCM ×HCF = PRODUCT OF TWO NUMBERS so 1296×36= xy.

46656=xy. No.s which can divide 46656 are 2,3,4,6,7,9,36,12,1296,46656. So around 9 pairs can be formed. If we take two numbers in one pair then 5 pairs can be formed.

Hope it helps
