LCM of:

Least Common Multiple of 78/72,15/10,988/676

Given numbers are 78/72,15/10,988/676

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 78,15,988

Least Common Multiple of Numerators i.e. LCM of 78,15,988 is 14820.

GCF of Denominators means GCF of 72,10,676 as per the given fractions.

GCF of 72,10,676 is 2 as it is the largest common factor for these numbers.

Lets's calculate LCM of 78,15,988

LCM of Fractions 78/72,15/10,988/676 is 7410

2 78, 15, 988
3 39, 15, 494
13 13, 5, 494
1, 5, 38

∴ So the LCM of the given numbers is 2 x 3 x 13 x 1 x 5 x 38 = 14820

Least Common Multiple of 78,15,988 with GCF Formula

Least Common Multiple of 78,15,988 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 78,15,988 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(78,15,988) = 1

common factors(in case of two or more numbers have common factors) = 78

GCF(78,15,988) x common factors =1 x 78 = 78

LCM(78,15,988) = ( 78 × 15 × 988 ) / 78

LCM(78,15,988) = 1155960 / 78

LCM(78,15,988) = 14820


Lets's calculate GCF of 72,10,676

2 72, 10, 676
36, 5, 338

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 14820/2

Therefore the LCM of Fractions 78/72,15/10,988/676 is 7410
