Least Common Multiple of 648/15,5600/420

Given numbers are 648/15,5600/420

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 648,5600

Least Common Multiple of Numerators i.e. LCM of 648,5600 is 453600.

GCF of Denominators means GCF of 15,420 as per the given fractions.

GCF of 15,420 is 15 as it is the largest common factor for these numbers.

Lets's calculate LCM of 648,5600

LCM of Fractions 648/15,5600/420 is 30240

2 648, 5600
2 324, 2800
2 162, 1400
81, 700

∴ So the LCM of the given numbers is 2 x 2 x 2 x 81 x 700 = 453600

Least Common Multiple of 648,5600 with GCF Formula

Least Common Multiple of 648,5600 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 648,5600 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(648,5600) = 8

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

GCF(648,5600) x common factors =8 x 1 = 8

LCM(648,5600) = ( 648 × 5600 ) / 8

LCM(648,5600) = 3628800 / 8

LCM(648,5600) = 453600


Lets's calculate GCF of 15,420

3 15, 420
5 5, 140
1, 28

∴ So the GCF of the given numbers is 3 x 5 = 15

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 453600/15

Therefore the LCM of Fractions 648/15,5600/420 is 30240
