LCM of 80, 17, 68, 990

Least common multiple or lowest common denominator (lcd) can be calculated in three ways

LCM of:

Least Common Multiple of 80,17,68,990

Least Common Multiple (LCM) of 80,17,68,990 is 134640

2 80, 17, 68, 990
2 40, 17, 34, 495
5 20, 17, 17, 495
17 4, 17, 17, 99
4, 1, 1, 99

∴ So the LCM of the given numbers is 2 x 2 x 5 x 17 x 4 x 1 x 1 x 99 = 134640

Least Common Multiple of 80,17,68,990 with GCF Formula

The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).

We need to calculate greatest common factor of 80,17,68,990 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(80,17,68,990) = 1

common factors(in case of two or more numbers have common factors) = 680

GCF(80,17,68,990) x common factors =1 x 680 = 680

LCM(80,17,68,990) = ( 80 × 17 × 68 × 990 ) / 680

LCM(80,17,68,990) = 91555200 / 680

LCM(80,17,68,990) = 134640

∴ Least Common Multiple of 80,17,68,990 is 134640
