Least Common Multiple of 22,20,99,81

Least Common Multiple (LCM) of 22,20,99,81 is 17820

2	22, 20, 99, 81
3	11, 10, 99, 81
3	11, 10, 33, 27
11	11, 10, 11, 9
	1, 10, 1, 9

∴ So the LCM of the given numbers is 2 x 3 x 3 x 11 x 1 x 10 x 1 x 9 = 17820

Least Common Multiple of 22,20,99,81 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 22,20,99,81 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(22,20,99,81) = 1

common factors(in case of two or more numbers have common factors) = 198

GCF(22,20,99,81) x common factors =1 x 198 = 198

LCM(22,20,99,81) = ( 22 × 20 × 99 × 81 ) / 198

LCM(22,20,99,81) = 3528360 / 198

LCM(22,20,99,81) = 17820

∴ Least Common Multiple of 22,20,99,81 is 17820
