Least Common Multiple of 70, 80, 66, 20 with GCF Formula

Least Common Multiple of 70,80,66,20

Least Common Multiple (LCM) of 70,80,66,20 is 18480

2	70, 80, 66, 20
2	35, 40, 33, 10
5	35, 20, 33, 5
	7, 4, 33, 1

∴ So the LCM of the given numbers is 2 x 2 x 5 x 7 x 4 x 33 x 1 = 18480

Least Common Multiple of 70,80,66,20 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 70,80,66,20 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(70,80,66,20) = 2

common factors(in case of two or more numbers have common factors) = 200

GCF(70,80,66,20) x common factors =2 x 200 = 400

LCM(70,80,66,20) = ( 70 × 80 × 66 × 20 ) / 400

LCM(70,80,66,20) = 7392000 / 400

LCM(70,80,66,20) = 18480

∴ Least Common Multiple of 70,80,66,20 is 18480
