Least Common Multiple of 77,62,66,420

Least Common Multiple (LCM) of 77,62,66,420 is 143220

2	77, 62, 66, 420
3	77, 31, 33, 210
7	77, 31, 11, 70
11	11, 31, 11, 10
	1, 31, 1, 10

∴ So the LCM of the given numbers is 2 x 3 x 7 x 11 x 1 x 31 x 1 x 10 = 143220

Least Common Multiple of 77,62,66,420 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 77,62,66,420 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(77,62,66,420) = 1

common factors(in case of two or more numbers have common factors) = 924

GCF(77,62,66,420) x common factors =1 x 924 = 924

LCM(77,62,66,420) = ( 77 × 62 × 66 × 420 ) / 924

LCM(77,62,66,420) = 132335280 / 924

LCM(77,62,66,420) = 143220

∴ Least Common Multiple of 77,62,66,420 is 143220
