LCM of:

Least Common Multiple of 68/87,40/15,528/72

Given numbers are 68/87,40/15,528/72

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 68,40,528

Least Common Multiple of Numerators i.e. LCM of 68,40,528 is 44880.

GCF of Denominators means GCF of 87,15,72 as per the given fractions.

GCF of 87,15,72 is 3 as it is the largest common factor for these numbers.

Lets's calculate LCM of 68,40,528

LCM of Fractions 68/87,40/15,528/72 is 14960

2 68, 40, 528
2 34, 20, 264
2 17, 10, 132
17, 5, 66

∴ So the LCM of the given numbers is 2 x 2 x 2 x 17 x 5 x 66 = 44880

Least Common Multiple of 68,40,528 with GCF Formula

Least Common Multiple of 68,40,528 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 68,40,528 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(68,40,528) = 4

common factors(in case of two or more numbers have common factors) = 8

GCF(68,40,528) x common factors =4 x 8 = 32

LCM(68,40,528) = ( 68 × 40 × 528 ) / 32

LCM(68,40,528) = 1436160 / 32

LCM(68,40,528) = 44880


Lets's calculate GCF of 87,15,72

3 87, 15, 72
29, 5, 24

∴ So the GCF of the given numbers is 3 = 3

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 44880/3

Therefore the LCM of Fractions 68/87,40/15,528/72 is 14960
