Least common multiple (LCM) of 10, 84, 14, 640 is 13440.

LCM(10, 84, 14, 640) = 13440

LCM of 10, 84, 14, 640

Least common multiple or lowest common denominator (lcd) can be calculated in three ways

LCM of:

Least Common Multiple of 10,84,14,640

Least Common Multiple (LCM) of 10,84,14,640 is 13440

2 10, 84, 14, 640
2 5, 42, 7, 320
5 5, 21, 7, 160
7 1, 21, 7, 32
1, 3, 1, 32

∴ So the LCM of the given numbers is 2 x 2 x 5 x 7 x 1 x 3 x 1 x 32 = 13440

Least Common Multiple of 10,84,14,640 with GCF Formula

The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).

We need to calculate greatest common factor of 10,84,14,640 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(10,84,14,640) = 2

common factors(in case of two or more numbers have common factors) = 280

GCF(10,84,14,640) x common factors =2 x 280 = 560

LCM(10,84,14,640) = ( 10 × 84 × 14 × 640 ) / 560

LCM(10,84,14,640) = 7526400 / 560

LCM(10,84,14,640) = 13440

∴ Least Common Multiple of 10,84,14,640 is 13440
