LCM of 21, 72, 80, 763

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

LCM of:

Least Common Multiple of 21,72,80,763

Least Common Multiple (LCM) of 21,72,80,763 is 549360

2 21, 72, 80, 763
2 21, 36, 40, 763
2 21, 18, 20, 763
3 21, 9, 10, 763
7 7, 3, 10, 763
1, 3, 10, 109

∴ So the LCM of the given numbers is 2 x 2 x 2 x 3 x 7 x 1 x 3 x 10 x 109 = 549360

Least Common Multiple of 21,72,80,763 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 21,72,80,763 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(21,72,80,763) = 1

common factors(in case of two or more numbers have common factors) = 168

GCF(21,72,80,763) x common factors =1 x 168 = 168

LCM(21,72,80,763) = ( 21 × 72 × 80 × 763 ) / 168

LCM(21,72,80,763) = 92292480 / 168

LCM(21,72,80,763) = 549360

∴ Least Common Multiple of 21,72,80,763 is 549360
