LCM of:

Least Common Multiple of 257/456,158/460

Given numbers are 257/456,158/460

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 257,158

Least Common Multiple of Numerators i.e. LCM of 257,158 is 40606.

GCF of Denominators means GCF of 456,460 as per the given fractions.

GCF of 456,460 is 4 as it is the largest common factor for these numbers.

Lets's calculate LCM of 257,158

LCM of Fractions 257/456,158/460 is 40606/4

Given numbers has no common factors except 1. So, there LCM is their product i.e 40606

Least Common Multiple of 257,158 with GCF Formula

Least Common Multiple of 257,158 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 257,158 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(257,158) = 1

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

GCF(257,158) x common factors =1 x 1 = 1

LCM(257,158) = ( 257 × 158 ) / 1

LCM(257,158) = 40606 / 1

LCM(257,158) = 40606


Lets's calculate GCF of 456,460

2 456, 460
2 228, 230
114, 115

∴ So the GCF of the given numbers is 2 x 2 = 4

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 40606/4

Therefore the LCM of Fractions 257/456,158/460 is 40606/4
