Least Common Multiple of 645/44,561/12,387/89

Given numbers are 645/44,561/12,387/89

Formula to find LCM of Fractions is

LCM = LCM of Numerators/GCF of Denominators

As per the formula LCM of Fractions let’s split into two parts and find the LCM of Numerators and GCF of Denominators

In the given fractions LCM of Numerators means LCM of 645,561,387

Least Common Multiple of Numerators i.e. LCM of 645,561,387 is 361845.

GCF of Denominators means GCF of 44,12,89 as per the given fractions.

GCF of 44,12,89 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 645,561,387

LCM of Fractions 645/44,561/12,387/89 is 361845

3 645, 561, 387
43 215, 187, 129
5, 187, 3

∴ So the LCM of the given numbers is 3 x 43 x 5 x 187 x 3 = 361845

Least Common Multiple of 645,561,387 with GCF Formula

Least Common Multiple of 645,561,387 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 645,561,387 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(645,561,387) = 3

common factors(in case of two or more numbers have common factors) = 129

GCF(645,561,387) x common factors =3 x 129 = 387

LCM(645,561,387) = ( 645 × 561 × 387 ) / 387

LCM(645,561,387) = 140034015 / 387

LCM(645,561,387) = 361845


Lets's calculate GCF of 44,12,89

∴ So GCF of numbers is 1 because of no common factors present between them.

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 361845/1

Therefore the LCM of Fractions 645/44,561/12,387/89 is 361845
