Least Common Multiple of 688/76,828/39,509/40

Given numbers are 688/76,828/39,509/40

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 688,828,509

Least Common Multiple of Numerators i.e. LCM of 688,828,509 is 72489744.

GCF of Denominators means GCF of 76,39,40 as per the given fractions.

GCF of 76,39,40 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 688,828,509

LCM of Fractions 688/76,828/39,509/40 is 72489744

2 688, 828, 509
2 344, 414, 509
172, 207, 509

∴ So the LCM of the given numbers is 2 x 2 x 172 x 207 x 509 = 72489744

Least Common Multiple of 688,828,509 with GCF Formula

Least Common Multiple of 688,828,509 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 688,828,509 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(688,828,509) = 1

common factors(in case of two or more numbers have common factors) = 4

GCF(688,828,509) x common factors =1 x 4 = 4

LCM(688,828,509) = ( 688 × 828 × 509 ) / 4

LCM(688,828,509) = 289958976 / 4

LCM(688,828,509) = 72489744


Lets's calculate GCF of 76,39,40

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 72489744/1

Therefore the LCM of Fractions 688/76,828/39,509/40 is 72489744
