Least Common Multiple of 17/74,28/31,66/71,647/14

Given numbers are 17/74,28/31,66/71,647/14

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 17,28,66,647

Least Common Multiple of Numerators i.e. LCM of 17,28,66,647 is 10163076.

GCF of Denominators means GCF of 74,31,71,14 as per the given fractions.

GCF of 74,31,71,14 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 17,28,66,647

LCM of Fractions 17/74,28/31,66/71,647/14 is 10163076

2 17, 28, 66, 647
17, 14, 33, 647

∴ So the LCM of the given numbers is 2 x 17 x 14 x 33 x 647 = 10163076

Least Common Multiple of 17,28,66,647 with GCF Formula

Least Common Multiple of 17,28,66,647 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 17,28,66,647 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(17,28,66,647) = 1

common factors(in case of two or more numbers have common factors) = 2

GCF(17,28,66,647) x common factors =1 x 2 = 2

LCM(17,28,66,647) = ( 17 × 28 × 66 × 647 ) / 2

LCM(17,28,66,647) = 20326152 / 2

LCM(17,28,66,647) = 10163076


Lets's calculate GCF of 74,31,71,14

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 10163076/1

Therefore the LCM of Fractions 17/74,28/31,66/71,647/14 is 10163076
