Least Common Multiple of 28/621,88/783,258/531

Given numbers are 28/621,88/783,258/531

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 28,88,258

Least Common Multiple of Numerators i.e. LCM of 28,88,258 is 79464.

GCF of Denominators means GCF of 621,783,531 as per the given fractions.

GCF of 621,783,531 is 9 as it is the largest common factor for these numbers.

Lets's calculate LCM of 28,88,258

LCM of Fractions 28/621,88/783,258/531 is 79464/9

2 28, 88, 258
2 14, 44, 129
7, 22, 129

∴ So the LCM of the given numbers is 2 x 2 x 7 x 22 x 129 = 79464

Least Common Multiple of 28,88,258 with GCF Formula

Least Common Multiple of 28,88,258 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 28,88,258 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(28,88,258) = 2

common factors(in case of two or more numbers have common factors) = 4

GCF(28,88,258) x common factors =2 x 4 = 8

LCM(28,88,258) = ( 28 × 88 × 258 ) / 8

LCM(28,88,258) = 635712 / 8

LCM(28,88,258) = 79464


Lets's calculate GCF of 621,783,531

3 621, 783, 531
3 207, 261, 177
69, 87, 59

∴ So the GCF of the given numbers is 3 x 3 = 9

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 79464/9

Therefore the LCM of Fractions 28/621,88/783,258/531 is 79464/9
