LCM of 9/18, 12/42, 252/60

Enter two or more fractions separated by "commas"

Ex: 2/3, 5/7 or 3/5, 5/9, 7/3

LCM of:

Least Common Multiple of 9/18,12/42,252/60

Given numbers are 9/18,12/42,252/60

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 9,12,252

Least Common Multiple of Numerators i.e. LCM of 9,12,252 is 252.

GCF of Denominators means GCF of 18,42,60 as per the given fractions.

GCF of 18,42,60 is 6 as it is the largest common factor for these numbers.

Lets's calculate LCM of 9,12,252

LCM of Fractions 9/18,12/42,252/60 is 42

2 9, 12, 252
2 9, 6, 126
3 9, 3, 63
3 1, 3, 21
1, 1, 7

∴ So the LCM of the given numbers is 2 x 2 x 3 x 3 x 1 x 1 x 7 = 252

Least Common Multiple of 9,12,252 with GCF Formula

Least Common Multiple of 9,12,252 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 9,12,252 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(9,12,252) = 3

common factors(in case of two or more numbers have common factors) = 36

GCF(9,12,252) x common factors =3 x 36 = 108

LCM(9,12,252) = ( 9 × 12 × 252 ) / 108

LCM(9,12,252) = 27216 / 108

LCM(9,12,252) = 252


Lets's calculate GCF of 18,42,60

2 18, 42, 60
3 9, 21, 30
3, 7, 10

∴ So the GCF of the given numbers is 2 x 3 = 6

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 252/6

Therefore the LCM of Fractions 9/18,12/42,252/60 is 42
