Question

find the LCM [x,y] for each of the following.Show your solution.
1.x=2²×3×5⁴,y=3 to the power of 7×5²×11³​

Answer 1

Answer:

First we find the H.C.F of 391 and 667.

Remainder of 667/391 = 276

Remainder of 391/276 =115

Remainder of 276/115 = 46

Remainder of 115/46 = 23

Remainder of 46/23= 0

∴ H.C.F. of 391, 667 = 23

∴ 391/667 =( 391/23)/ (667/23)= 17/29
