Least Common Multiple of 40, 42, 50, 856 with GCF Formula

Least Common Multiple of 40,42,50,856

Least Common Multiple (LCM) of 40,42,50,856 is 449400

2	40, 42, 50, 856
2	20, 21, 25, 428
2	10, 21, 25, 214
5	5, 21, 25, 107
	1, 21, 5, 107

∴ So the LCM of the given numbers is 2 x 2 x 2 x 5 x 1 x 21 x 5 x 107 = 449400

Least Common Multiple of 40,42,50,856 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 40,42,50,856 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(40,42,50,856) = 2

common factors(in case of two or more numbers have common factors) = 80

GCF(40,42,50,856) x common factors =2 x 80 = 160

LCM(40,42,50,856) = ( 40 × 42 × 50 × 856 ) / 160

LCM(40,42,50,856) = 71904000 / 160

LCM(40,42,50,856) = 449400

∴ Least Common Multiple of 40,42,50,856 is 449400
