Greatest Common Factor of 69/33,12/70

Given fractions are 69/33,12/70

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 69,12

Greatest Common Factor of Numerators i.e. GCF of 69,12 is 3 .

LCM of Denominators means LCM of 33,70 as per the given fractions.

LCM of 33,70 is 2310 as it is the smallest common factor for both these numbers.

Lets's calculate GCF of 69,12

GCF of Fractions 69/33,12/70 is 3/2310

3 69, 12
23, 4

∴ So the GCF of the given numbers is 3 = 3

Greatest Common Factor

We found the factors 69,12 . The biggest common factor number is the GCF number.
So the greatest common factor 69,12 is 3.

Lets's calculate LCM of 33,70

Given numbers has no common factors except 1. So, there LCM is their product i.e 2310

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/2310

Therefore, the GCF of Fractions 69/33,12/70 is 3/2310

Least Common Multiple of 33,70 with GCF Formula

Least Common Multiple of 33,70 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 33,70 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(33,70) = 1

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

GCF(33,70) x common factors =1 x 1 = 1

LCM(33,70) = ( 33 × 70 ) / 1

LCM(33,70) = 2310 / 1

LCM(33,70) = 2310
