Greatest Common Factor of 7/407,8/321

Given fractions are 7/407,8/321

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 7,8

Greatest Common Factor of Numerators i.e. GCF of 7,8 is 1 .

LCM of Denominators means LCM of 407,321 as per the given fractions.

LCM of 407,321 is 130647 as it is the smallest common factor for both these numbers.

Lets's calculate GCF of 7,8

GCF of Fractions 7/407,8/321 is 1/130647

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

Greatest Common Factor

We found the factors 7,8 . The biggest common factor number is the GCF number.
So the greatest common factor 7,8 is 1.

Lets's calculate LCM of 407,321

Given numbers has no common factors except 1. So, there LCM is their product i.e 130647

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/130647

Therefore, the GCF of Fractions 7/407,8/321 is 1/130647

Least Common Multiple of 407,321 with GCF Formula

Least Common Multiple of 407,321 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 407,321 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(407,321) = 1

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

GCF(407,321) x common factors =1 x 1 = 1

LCM(407,321) = ( 407 × 321 ) / 1

LCM(407,321) = 130647 / 1

LCM(407,321) = 130647
