LCM of:

Least Common Multiple of 51/90,32/69,251/78

Given numbers are 51/90,32/69,251/78

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 51,32,251

Least Common Multiple of Numerators i.e. LCM of 51,32,251 is 409632.

GCF of Denominators means GCF of 90,69,78 as per the given fractions.

GCF of 90,69,78 is 3 as it is the largest common factor for these numbers.

Lets's calculate LCM of 51,32,251

LCM of Fractions 51/90,32/69,251/78 is 136544

Given numbers has no common factors except 1. So, there LCM is their product i.e 409632

Least Common Multiple of 51,32,251 with GCF Formula

Least Common Multiple of 51,32,251 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 51,32,251 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(51,32,251) = 1

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

GCF(51,32,251) x common factors =1 x 1 = 1

LCM(51,32,251) = ( 51 × 32 × 251 ) / 1

LCM(51,32,251) = 409632 / 1

LCM(51,32,251) = 409632


Lets's calculate GCF of 90,69,78

3 90, 69, 78
30, 23, 26

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 409632/3

Therefore the LCM of Fractions 51/90,32/69,251/78 is 136544
