LCM of:

Least Common Multiple of 72/40,66/76,31/488

Given numbers are 72/40,66/76,31/488

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 72,66,31

Least Common Multiple of Numerators i.e. LCM of 72,66,31 is 24552.

GCF of Denominators means GCF of 40,76,488 as per the given fractions.

GCF of 40,76,488 is 4 as it is the largest common factor for these numbers.

Lets's calculate LCM of 72,66,31

LCM of Fractions 72/40,66/76,31/488 is 6138

2 72, 66, 31
3 36, 33, 31
12, 11, 31

∴ So the LCM of the given numbers is 2 x 3 x 12 x 11 x 31 = 24552

Least Common Multiple of 72,66,31 with GCF Formula

Least Common Multiple of 72,66,31 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 72,66,31 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(72,66,31) = 1

common factors(in case of two or more numbers have common factors) = 6

GCF(72,66,31) x common factors =1 x 6 = 6

LCM(72,66,31) = ( 72 × 66 × 31 ) / 6

LCM(72,66,31) = 147312 / 6

LCM(72,66,31) = 24552


Lets's calculate GCF of 40,76,488

2 40, 76, 488
2 20, 38, 244
10, 19, 122

∴ So the GCF of the given numbers is 2 x 2 = 4

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 24552/4

Therefore the LCM of Fractions 72/40,66/76,31/488 is 6138
