LCM of:

Least Common Multiple of 31,28,494,620

Least Common Multiple (LCM) of 31,28,494,620 is 1071980

2 31, 28, 494, 620
2 31, 14, 247, 310
31 31, 7, 247, 155
1, 7, 247, 5

∴ So the LCM of the given numbers is 2 x 2 x 31 x 1 x 7 x 247 x 5 = 1071980

Least Common Multiple of 31,28,494,620 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 31,28,494,620 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(31,28,494,620) = 1

common factors(in case of two or more numbers have common factors) = 248

GCF(31,28,494,620) x common factors =1 x 248 = 248

LCM(31,28,494,620) = ( 31 × 28 × 494 × 620 ) / 248

LCM(31,28,494,620) = 265851040 / 248

LCM(31,28,494,620) = 1071980

∴ Least Common Multiple of 31,28,494,620 is 1071980
