Least Common Multiple of 80,90,98,140

Least Common Multiple (LCM) of 80,90,98,140 is 35280

2	80, 90, 98, 140
2	40, 45, 49, 70
5	20, 45, 49, 35
7	4, 9, 49, 7
	4, 9, 1, 7

∴ So the LCM of the given numbers is 2 x 2 x 5 x 7 x 4 x 9 x 1 x 7 = 35280

Least Common Multiple of 80,90,98,140 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 80,90,98,140 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(80,90,98,140) = 2

common factors(in case of two or more numbers have common factors) = 1400

GCF(80,90,98,140) x common factors =2 x 1400 = 2800

LCM(80,90,98,140) = ( 80 × 90 × 98 × 140 ) / 2800

LCM(80,90,98,140) = 98784000 / 2800

LCM(80,90,98,140) = 35280

∴ Least Common Multiple of 80,90,98,140 is 35280
