Least Common Multiple of 61/45,630/19,840/880

Given numbers are 61/45,630/19,840/880

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 61,630,840

Least Common Multiple of Numerators i.e. LCM of 61,630,840 is 153720.

GCF of Denominators means GCF of 45,19,880 as per the given fractions.

GCF of 45,19,880 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 61,630,840

LCM of Fractions 61/45,630/19,840/880 is 153720

2 61, 630, 840
3 61, 315, 420
5 61, 105, 140
7 61, 21, 28
61, 3, 4

∴ So the LCM of the given numbers is 2 x 3 x 5 x 7 x 61 x 3 x 4 = 153720

Least Common Multiple of 61,630,840 with GCF Formula

Least Common Multiple of 61,630,840 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 61,630,840 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(61,630,840) = 1

common factors(in case of two or more numbers have common factors) = 210

GCF(61,630,840) x common factors =1 x 210 = 210

LCM(61,630,840) = ( 61 × 630 × 840 ) / 210

LCM(61,630,840) = 32281200 / 210

LCM(61,630,840) = 153720


Lets's calculate GCF of 45,19,880

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 153720/1

Therefore the LCM of Fractions 61/45,630/19,840/880 is 153720
