Least Common Multiple of 20, 73, 80, 240 with GCF Formula

Least Common Multiple of 20,73,80,240

Least Common Multiple (LCM) of 20,73,80,240 is 17520

2	20, 73, 80, 240
2	10, 73, 40, 120
2	5, 73, 20, 60
2	5, 73, 10, 30
5	5, 73, 5, 15
	1, 73, 1, 3

∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 5 x 1 x 73 x 1 x 3 = 17520

Least Common Multiple of 20,73,80,240 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 20,73,80,240 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(20,73,80,240) = 1

common factors(in case of two or more numbers have common factors) = 1600

GCF(20,73,80,240) x common factors =1 x 1600 = 1600

LCM(20,73,80,240) = ( 20 × 73 × 80 × 240 ) / 1600

LCM(20,73,80,240) = 28032000 / 1600

LCM(20,73,80,240) = 17520

∴ Least Common Multiple of 20,73,80,240 is 17520
