LCM of:

Least Common Multiple of 680,580

Least Common Multiple (LCM) of 680,580 is 19720

2 680, 580
2 340, 290
5 170, 145
34, 29

∴ So the LCM of the given numbers is 2 x 2 x 5 x 34 x 29 = 19720

Least Common Multiple of 680,580 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 680,580 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(680,580) = 20

common factors(in case of two or more numbers have common factors) = 1

GCF(680,580) x common factors =20 x 1 = 20

LCM(680,580) = ( 680 × 580 ) / 20

LCM(680,580) = 394400 / 20

LCM(680,580) = 19720

∴ Least Common Multiple of 680,580 is 19720
