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

GCF of:

Greatest Common Factor of 36/2,80/1

Given fractions are 36/2,80/1

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 36,80

Greatest Common Factor of Numerators i.e. GCF of 36,80 is 4 .

LCM of Denominators means LCM of 2,1 as per the given fractions.

LCM of 2,1 is 2 as it is the smallest common factor for both these numbers.

Lets's calculate GCF of 36,80

GCF of Fractions 36/2,80/1 is 4/2

2 36, 80
2 18, 40
9, 20

∴ So the GCF of the given numbers is 2 x 2 = 4

Factors of 36

List of positive integer factors of 36 that divides 36 without a remainder.

1,2,3,4,6,9,12,18,36

Factors of 80

List of positive integer factors of 80 that divides 80 without a remainder.

1,2,4,5,8,10,16,20,40,80

Greatest Common Factor

We found the factors 36,80 . The biggest common factor number is the GCF number.
So the greatest common factor 36,80 is 4.

Lets's calculate LCM of 2,1

Given numbers has no common factors except 1. So, there LCM is their product i.e 2

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/2

Therefore, the GCF of Fractions 36/2,80/1 is 4/2

Least Common Multiple of 2,1 with GCF Formula

Least Common Multiple of 2,1 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 2,1 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(2,1) = 1

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

GCF(2,1) x common factors =1 x 1 = 1

LCM(2,1) = ( 2 × 1 ) / 1

LCM(2,1) = 2 / 1

LCM(2,1) = 2
