Least Common Multiple of 66/79,70/78,90/29,84/356

Given numbers are 66/79,70/78,90/29,84/356

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 66,70,90,84

Least Common Multiple of Numerators i.e. LCM of 66,70,90,84 is 13860.

GCF of Denominators means GCF of 79,78,29,356 as per the given fractions.

GCF of 79,78,29,356 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 66,70,90,84

LCM of Fractions 66/79,70/78,90/29,84/356 is 13860

2 66, 70, 90, 84
3 33, 35, 45, 42
5 11, 35, 15, 14
7 11, 7, 3, 14
11, 1, 3, 2

∴ So the LCM of the given numbers is 2 x 3 x 5 x 7 x 11 x 1 x 3 x 2 = 13860

Least Common Multiple of 66,70,90,84 with GCF Formula

Least Common Multiple of 66,70,90,84 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 66,70,90,84 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(66,70,90,84) = 2

common factors(in case of two or more numbers have common factors) = 1260

GCF(66,70,90,84) x common factors =2 x 1260 = 2520

LCM(66,70,90,84) = ( 66 × 70 × 90 × 84 ) / 2520

LCM(66,70,90,84) = 34927200 / 2520

LCM(66,70,90,84) = 13860


Lets's calculate GCF of 79,78,29,356

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 13860/1

Therefore the LCM of Fractions 66/79,70/78,90/29,84/356 is 13860
