Least Common Multiple of 69/351,51/499,391/609

Given numbers are 69/351,51/499,391/609

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 69,51,391

Least Common Multiple of Numerators i.e. LCM of 69,51,391 is 1173.

GCF of Denominators means GCF of 351,499,609 as per the given fractions.

GCF of 351,499,609 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 69,51,391

LCM of Fractions 69/351,51/499,391/609 is 1173

3 69, 51, 391
17 23, 17, 391
23 23, 1, 23
1, 1, 1

∴ So the LCM of the given numbers is 3 x 17 x 23 x 1 x 1 x 1 = 1173

Least Common Multiple of 69,51,391 with GCF Formula

Least Common Multiple of 69,51,391 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 69,51,391 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(69,51,391) = 1

common factors(in case of two or more numbers have common factors) = 1173

GCF(69,51,391) x common factors =1 x 1173 = 1173

LCM(69,51,391) = ( 69 × 51 × 391 ) / 1173

LCM(69,51,391) = 1375929 / 1173

LCM(69,51,391) = 1173


Lets's calculate GCF of 351,499,609

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 1173/1

Therefore the LCM of Fractions 69/351,51/499,391/609 is 1173
