Least Common Multiple of 55/31,36/47,24/52,20/780

Given numbers are 55/31,36/47,24/52,20/780

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 55,36,24,20

Least Common Multiple of Numerators i.e. LCM of 55,36,24,20 is 3960.

GCF of Denominators means GCF of 31,47,52,780 as per the given fractions.

GCF of 31,47,52,780 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 55,36,24,20

LCM of Fractions 55/31,36/47,24/52,20/780 is 3960

2 55, 36, 24, 20
2 55, 18, 12, 10
3 55, 9, 6, 5
5 55, 3, 2, 5
11, 3, 2, 1

∴ So the LCM of the given numbers is 2 x 2 x 3 x 5 x 11 x 3 x 2 x 1 = 3960

Least Common Multiple of 55,36,24,20 with GCF Formula

Least Common Multiple of 55,36,24,20 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 55,36,24,20 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(55,36,24,20) = 1

common factors(in case of two or more numbers have common factors) = 240

GCF(55,36,24,20) x common factors =1 x 240 = 240

LCM(55,36,24,20) = ( 55 × 36 × 24 × 20 ) / 240

LCM(55,36,24,20) = 950400 / 240

LCM(55,36,24,20) = 3960


Lets's calculate GCF of 31,47,52,780

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 3960/1

Therefore the LCM of Fractions 55/31,36/47,24/52,20/780 is 3960
