GCF of:

Greatest Common Factor of 2/64,3/70,20/33,11/391

Given fractions are 2/64,3/70,20/33,11/391

Formula to find GCF of Fractions is

GCF = GCF of Numerators/LCM of Denominators

As per the formula GCF of Fractions let’s split into two parts and find the GCF of Numerators and LCM of Denominators

In the given fractions GCF of Numerators means GCF of 2,3,20,11

Greatest Common Factor of Numerators i.e. GCF of 2,3,20,11 is 1 .

LCM of Denominators means LCM of 64,70,33,391 as per the given fractions.

LCM of 64,70,33,391 is 28902720 as it is the smallest common factor for both these numbers.

Lets's calculate GCF of 2,3,20,11

GCF of Fractions 2/64,3/70,20/33,11/391 is 1/28902720

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

Lets's calculate LCM of 64,70,33,391

2 64, 70, 33, 391
32, 35, 33, 391

∴ So the LCM of the given numbers is 2 x 32 x 35 x 33 x 391 = 28902720

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/28902720

Therefore, the GCF of Fractions 2/64,3/70,20/33,11/391 is 1/28902720

Least Common Multiple of 64,70,33,391 with GCF Formula

Least Common Multiple of 64,70,33,391 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 64,70,33,391 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(64,70,33,391) = 1

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

GCF(64,70,33,391) x common factors =1 x 2 = 2

LCM(64,70,33,391) = ( 64 × 70 × 33 × 391 ) / 2

LCM(64,70,33,391) = 57805440 / 2

LCM(64,70,33,391) = 28902720
