Least Common Multiple of 78/18,62/86,630/380

Given numbers are 78/18,62/86,630/380

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 78,62,630

Least Common Multiple of Numerators i.e. LCM of 78,62,630 is 253890.

GCF of Denominators means GCF of 18,86,380 as per the given fractions.

GCF of 18,86,380 is 2 as it is the largest common factor for these numbers.

Lets's calculate LCM of 78,62,630

LCM of Fractions 78/18,62/86,630/380 is 126945

2 78, 62, 630
3 39, 31, 315
13, 31, 105

∴ So the LCM of the given numbers is 2 x 3 x 13 x 31 x 105 = 253890

Least Common Multiple of 78,62,630 with GCF Formula

Least Common Multiple of 78,62,630 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 78,62,630 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(78,62,630) = 2

common factors(in case of two or more numbers have common factors) = 6

GCF(78,62,630) x common factors =2 x 6 = 12

LCM(78,62,630) = ( 78 × 62 × 630 ) / 12

LCM(78,62,630) = 3046680 / 12

LCM(78,62,630) = 253890


Lets's calculate GCF of 18,86,380

2 18, 86, 380
9, 43, 190

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 253890/2

Therefore the LCM of Fractions 78/18,62/86,630/380 is 126945
