Least Common Multiple of 72/79,84/66,70/28,126/74

Given numbers are 72/79,84/66,70/28,126/74

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 72,84,70,126

Least Common Multiple of Numerators i.e. LCM of 72,84,70,126 is 2520.

GCF of Denominators means GCF of 79,66,28,74 as per the given fractions.

GCF of 79,66,28,74 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 72,84,70,126

LCM of Fractions 72/79,84/66,70/28,126/74 is 2520

2 72, 84, 70, 126
2 36, 42, 35, 63
3 18, 21, 35, 63
3 6, 7, 35, 21
7 2, 7, 35, 7
2, 1, 5, 1

∴ So the LCM of the given numbers is 2 x 2 x 3 x 3 x 7 x 2 x 1 x 5 x 1 = 2520

Least Common Multiple of 72,84,70,126 with GCF Formula

Least Common Multiple of 72,84,70,126 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 72,84,70,126 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(72,84,70,126) = 2

common factors(in case of two or more numbers have common factors) = 10584

GCF(72,84,70,126) x common factors =2 x 10584 = 21168

LCM(72,84,70,126) = ( 72 × 84 × 70 × 126 ) / 21168

LCM(72,84,70,126) = 53343360 / 21168

LCM(72,84,70,126) = 2520


Lets's calculate GCF of 79,66,28,74

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 2520/1

Therefore the LCM of Fractions 72/79,84/66,70/28,126/74 is 2520
