LCM of:

Least Common Multiple of 390/84,130/744

Given numbers are 390/84,130/744

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 390,130

Least Common Multiple of Numerators i.e. LCM of 390,130 is 390.

GCF of Denominators means GCF of 84,744 as per the given fractions.

GCF of 84,744 is 12 as it is the largest common factor for these numbers.

Lets's calculate LCM of 390,130

LCM of Fractions 390/84,130/744 is 390/12

2 390, 130
5 195, 65
13 39, 13
3, 1

∴ So the LCM of the given numbers is 2 x 5 x 13 x 3 x 1 = 390

Least Common Multiple of 390,130 with GCF Formula

Least Common Multiple of 390,130 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 390,130 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(390,130) = 130

common factors(in case of two or more numbers have common factors) = 1

GCF(390,130) x common factors =130 x 1 = 130

LCM(390,130) = ( 390 × 130 ) / 130

LCM(390,130) = 50700 / 130

LCM(390,130) = 390


Lets's calculate GCF of 84,744

2 84, 744
2 42, 372
3 21, 186
7, 62

∴ So the GCF of the given numbers is 2 x 2 x 3 = 12

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 390/12

Therefore the LCM of Fractions 390/84,130/744 is 390/12
