Least Common Multiple of 90,78,20,975

Least Common Multiple (LCM) of 90,78,20,975 is 11700

2	90, 78, 20, 975
3	45, 39, 10, 975
5	15, 13, 10, 325
13	3, 13, 2, 65
	3, 1, 2, 5

∴ So the LCM of the given numbers is 2 x 3 x 5 x 13 x 3 x 1 x 2 x 5 = 11700

Least Common Multiple of 90,78,20,975 with GCF Formula

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

We need to calculate greatest common factor of 90,78,20,975 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(90,78,20,975) = 1

common factors(in case of two or more numbers have common factors) = 11700

GCF(90,78,20,975) x common factors =1 x 11700 = 11700

LCM(90,78,20,975) = ( 90 × 78 × 20 × 975 ) / 11700

LCM(90,78,20,975) = 136890000 / 11700

LCM(90,78,20,975) = 11700

∴ Least Common Multiple of 90,78,20,975 is 11700
