GCF of:

Greatest Common Factor of 8/18,5/16,9/60,77/665

Given fractions are 8/18,5/16,9/60,77/665

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 8,5,9,77

Greatest Common Factor of Numerators i.e. GCF of 8,5,9,77 is 1 .

LCM of Denominators means LCM of 18,16,60,665 as per the given fractions.

LCM of 18,16,60,665 is 95760 as it is the smallest common factor for both these numbers.

Lets's calculate GCF of 8,5,9,77

GCF of Fractions 8/18,5/16,9/60,77/665 is 1/95760

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

Greatest Common Factor

We found the factors 8,5,9,77 . The biggest common factor number is the GCF number.
So the greatest common factor 8,5,9,77 is 1.

Lets's calculate LCM of 18,16,60,665

2 18, 16, 60, 665
2 9, 8, 30, 665
3 9, 4, 15, 665
5 3, 4, 5, 665
3, 4, 1, 133

∴ So the LCM of the given numbers is 2 x 2 x 3 x 5 x 3 x 4 x 1 x 133 = 95760

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/95760

Therefore, the GCF of Fractions 8/18,5/16,9/60,77/665 is 1/95760

Least Common Multiple of 18,16,60,665 with GCF Formula

Least Common Multiple of 18,16,60,665 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 18,16,60,665 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(18,16,60,665) = 1

common factors(in case of two or more numbers have common factors) = 120

GCF(18,16,60,665) x common factors =1 x 120 = 120

LCM(18,16,60,665) = ( 18 × 16 × 60 × 665 ) / 120

LCM(18,16,60,665) = 11491200 / 120

LCM(18,16,60,665) = 95760
