Least Common Multiple of 28/68,18/41,39/13,63/960

Given numbers are 28/68,18/41,39/13,63/960

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 28,18,39,63

Least Common Multiple of Numerators i.e. LCM of 28,18,39,63 is 3276.

GCF of Denominators means GCF of 68,41,13,960 as per the given fractions.

GCF of 68,41,13,960 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 28,18,39,63

LCM of Fractions 28/68,18/41,39/13,63/960 is 3276

2 28, 18, 39, 63
3 14, 9, 39, 63
3 14, 3, 13, 21
7 14, 1, 13, 7
2, 1, 13, 1

∴ So the LCM of the given numbers is 2 x 3 x 3 x 7 x 2 x 1 x 13 x 1 = 3276

Least Common Multiple of 28,18,39,63 with GCF Formula

Least Common Multiple of 28,18,39,63 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 28,18,39,63 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(28,18,39,63) = 1

common factors(in case of two or more numbers have common factors) = 378

GCF(28,18,39,63) x common factors =1 x 378 = 378

LCM(28,18,39,63) = ( 28 × 18 × 39 × 63 ) / 378

LCM(28,18,39,63) = 1238328 / 378

LCM(28,18,39,63) = 3276


Lets's calculate GCF of 68,41,13,960

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 3276/1

Therefore the LCM of Fractions 28/68,18/41,39/13,63/960 is 3276
