Least Common Multiple of 320/69,630/28,561/417

Given numbers are 320/69,630/28,561/417

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 320,630,561

Least Common Multiple of Numerators i.e. LCM of 320,630,561 is 3769920.

GCF of Denominators means GCF of 69,28,417 as per the given fractions.

GCF of 69,28,417 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 320,630,561

LCM of Fractions 320/69,630/28,561/417 is 3769920

2 320, 630, 561
3 160, 315, 561
5 160, 105, 187
32, 21, 187

∴ So the LCM of the given numbers is 2 x 3 x 5 x 32 x 21 x 187 = 3769920

Least Common Multiple of 320,630,561 with GCF Formula

Least Common Multiple of 320,630,561 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 320,630,561 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(320,630,561) = 1

common factors(in case of two or more numbers have common factors) = 30

GCF(320,630,561) x common factors =1 x 30 = 30

LCM(320,630,561) = ( 320 × 630 × 561 ) / 30

LCM(320,630,561) = 113097600 / 30

LCM(320,630,561) = 3769920


Lets's calculate GCF of 69,28,417

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 3769920/1

Therefore the LCM of Fractions 320/69,630/28,561/417 is 3769920
