Least Common Multiple of 20,21,89,102

Least Common Multiple (LCM) of 20,21,89,102 is 635460

2	20, 21, 89, 102
3	10, 21, 89, 51
	10, 7, 89, 17

∴ So the LCM of the given numbers is 2 x 3 x 10 x 7 x 89 x 17 = 635460

Least Common Multiple of 20,21,89,102 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 20,21,89,102 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(20,21,89,102) = 1

common factors(in case of two or more numbers have common factors) = 6

GCF(20,21,89,102) x common factors =1 x 6 = 6

LCM(20,21,89,102) = ( 20 × 21 × 89 × 102 ) / 6

LCM(20,21,89,102) = 3812760 / 6

LCM(20,21,89,102) = 635460

∴ Least Common Multiple of 20,21,89,102 is 635460
