Lets's calculate LCM of 398,489

LCM of Fractions 398/636,489/564 is 194622/12

Given numbers has no common factors except 1. So, there LCM is their product i.e 194622

Least Common Multiple of 398,489 with GCF Formula

Least Common Multiple of 398,489 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 398,489 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(398,489) = 1

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

GCF(398,489) x common factors =1 x 1 = 1

LCM(398,489) = ( 398 × 489 ) / 1

LCM(398,489) = 194622 / 1

LCM(398,489) = 194622


Lets's calculate GCF of 636,564

2 636, 564
2 318, 282
3 159, 141
53, 47

∴ So the GCF of the given numbers is 2 x 2 x 3 = 12

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 194622/12

Therefore the LCM of Fractions 398/636,489/564 is 194622/12
