Least Common Multiple of 84/83,46/81,90/38,28/457

Given numbers are 84/83,46/81,90/38,28/457

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 84,46,90,28

Least Common Multiple of Numerators i.e. LCM of 84,46,90,28 is 28980.

GCF of Denominators means GCF of 83,81,38,457 as per the given fractions.

GCF of 83,81,38,457 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 84,46,90,28

LCM of Fractions 84/83,46/81,90/38,28/457 is 28980

2 84, 46, 90, 28
2 42, 23, 45, 14
3 21, 23, 45, 7
7 7, 23, 15, 7
1, 23, 15, 1

∴ So the LCM of the given numbers is 2 x 2 x 3 x 7 x 1 x 23 x 15 x 1 = 28980

Least Common Multiple of 84,46,90,28 with GCF Formula

Least Common Multiple of 84,46,90,28 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 84,46,90,28 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(84,46,90,28) = 2

common factors(in case of two or more numbers have common factors) = 168

GCF(84,46,90,28) x common factors =2 x 168 = 336

LCM(84,46,90,28) = ( 84 × 46 × 90 × 28 ) / 336

LCM(84,46,90,28) = 9737280 / 336

LCM(84,46,90,28) = 28980


Lets's calculate GCF of 83,81,38,457

∴ So GCF of numbers is 1 because of no common factors present between them.

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 28980/1

Therefore the LCM of Fractions 84/83,46/81,90/38,28/457 is 28980
