LCM of:

Least Common Multiple of 28/457,56/629,115/648

Given numbers are 28/457,56/629,115/648

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 28,56,115

Least Common Multiple of Numerators i.e. LCM of 28,56,115 is 6440.

GCF of Denominators means GCF of 457,629,648 as per the given fractions.

GCF of 457,629,648 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 28,56,115

LCM of Fractions 28/457,56/629,115/648 is 6440

2 28, 56, 115
2 14, 28, 115
7 7, 14, 115
1, 2, 115

∴ So the LCM of the given numbers is 2 x 2 x 7 x 1 x 2 x 115 = 6440

Least Common Multiple of 28,56,115 with GCF Formula

Least Common Multiple of 28,56,115 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 28,56,115 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(28,56,115) = 1

common factors(in case of two or more numbers have common factors) = 28

GCF(28,56,115) x common factors =1 x 28 = 28

LCM(28,56,115) = ( 28 × 56 × 115 ) / 28

LCM(28,56,115) = 180320 / 28

LCM(28,56,115) = 6440


Lets's calculate GCF of 457,629,648

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 6440/1

Therefore the LCM of Fractions 28/457,56/629,115/648 is 6440
