Ex: 2/3, 5/7 or 3/5, 5/9, 7/3

GCF of:

Greatest Common Factor of 10/45,20/17,11/59,39/23

Given fractions are 10/45,20/17,11/59,39/23

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 10,20,11,39

Greatest Common Factor of Numerators i.e. GCF of 10,20,11,39 is 1 .

LCM of Denominators means LCM of 45,17,59,23 as per the given fractions.

LCM of 45,17,59,23 is 1038105 as it is the smallest common factor for both these numbers.

Lets's calculate GCF of 10,20,11,39

Lets's calculate LCM of 45,17,59,23

Given numbers has no common factors except 1. So, there LCM is their product i.e 1038105

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1038105

Therefore, the GCF of Fractions 10/45,20/17,11/59,39/23 is 1/1038105

Least Common Multiple of 45,17,59,23 with GCF Formula

Least Common Multiple of 45,17,59,23 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 45,17,59,23 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(45,17,59,23) = 1

common factors(in case of two or more numbers have common factors) = 1

GCF(45,17,59,23) x common factors =1 x 1 = 1

LCM(45,17,59,23) = ( 45 × 17 × 59 × 23 ) / 1

LCM(45,17,59,23) = 1038105 / 1

LCM(45,17,59,23) = 1038105
