Least Common Multiple of 15, 40, 42, 900 with GCF Formula

Least Common Multiple of 15,40,42,900

Least Common Multiple (LCM) of 15,40,42,900 is 12600

2	15, 40, 42, 900
2	15, 20, 21, 450
3	15, 10, 21, 225
5	5, 10, 7, 75
	1, 2, 7, 15

∴ So the LCM of the given numbers is 2 x 2 x 3 x 5 x 1 x 2 x 7 x 15 = 12600

Least Common Multiple of 15,40,42,900 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 15,40,42,900 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(15,40,42,900) = 1

common factors(in case of two or more numbers have common factors) = 1800

GCF(15,40,42,900) x common factors =1 x 1800 = 1800

LCM(15,40,42,900) = ( 15 × 40 × 42 × 900 ) / 1800

LCM(15,40,42,900) = 22680000 / 1800

LCM(15,40,42,900) = 12600

∴ Least Common Multiple of 15,40,42,900 is 12600
