GCF of:

Greatest Common Factor of 21/50,85/32,17/97,32/334

Given fractions are 21/50,85/32,17/97,32/334

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 21,85,17,32

Greatest Common Factor of Numerators i.e. GCF of 21,85,17,32 is 1 .

LCM of Denominators means LCM of 50,32,97,334 as per the given fractions.

LCM of 50,32,97,334 is 12959200 as it is the smallest common factor for both these numbers.

Lets's calculate GCF of 21,85,17,32

Greatest Common Factor

We found the factors 21,85,17,32 . The biggest common factor number is the GCF number.
So the greatest common factor 21,85,17,32 is 1.

Lets's calculate LCM of 50,32,97,334

2 50, 32, 97, 334
25, 16, 97, 167

∴ So the LCM of the given numbers is 2 x 25 x 16 x 97 x 167 = 12959200

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/12959200

Therefore, the GCF of Fractions 21/50,85/32,17/97,32/334 is 1/12959200

Least Common Multiple of 50,32,97,334 with GCF Formula

Least Common Multiple of 50,32,97,334 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 50,32,97,334 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(50,32,97,334) = 1

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

GCF(50,32,97,334) x common factors =1 x 4 = 4

LCM(50,32,97,334) = ( 50 × 32 × 97 × 334 ) / 4

LCM(50,32,97,334) = 51836800 / 4

LCM(50,32,97,334) = 12959200
