Least Common Multiple of 31, 44, 21, 480 with GCF Formula

Least Common Multiple of 31,44,21,480

Least Common Multiple (LCM) of 31,44,21,480 is 1145760

2	31, 44, 21, 480
2	31, 22, 21, 240
3	31, 11, 21, 120
	31, 11, 7, 40

∴ So the LCM of the given numbers is 2 x 2 x 3 x 31 x 11 x 7 x 40 = 1145760

Least Common Multiple of 31,44,21,480 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 31,44,21,480 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(31,44,21,480) = 1

common factors(in case of two or more numbers have common factors) = 12

GCF(31,44,21,480) x common factors =1 x 12 = 12

LCM(31,44,21,480) = ( 31 × 44 × 21 × 480 ) / 12

LCM(31,44,21,480) = 13749120 / 12

LCM(31,44,21,480) = 1145760

∴ Least Common Multiple of 31,44,21,480 is 1145760
