GCF of:

Greatest Common Factor of 53/49,54/84,18/42,34/10

Given fractions are 53/49,54/84,18/42,34/10

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 53,54,18,34

Greatest Common Factor of Numerators i.e. GCF of 53,54,18,34 is 1 .

LCM of Denominators means LCM of 49,84,42,10 as per the given fractions.

LCM of 49,84,42,10 is 2940 as it is the smallest common factor for both these numbers.

Lets's calculate GCF of 53,54,18,34

Greatest Common Factor

We found the factors 53,54,18,34 . The biggest common factor number is the GCF number.
So the greatest common factor 53,54,18,34 is 1.

Lets's calculate LCM of 49,84,42,10

2 49, 84, 42, 10
3 49, 42, 21, 5
7 49, 14, 7, 5
1, 2, 7, 5

∴ So the LCM of the given numbers is 2 x 3 x 7 x 1 x 2 x 7 x 5 = 2940

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2940

Therefore, the GCF of Fractions 53/49,54/84,18/42,34/10 is 1/2940

Least Common Multiple of 49,84,42,10 with GCF Formula

Least Common Multiple of 49,84,42,10 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 49,84,42,10 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(49,84,42,10) = 1

common factors(in case of two or more numbers have common factors) = 588

GCF(49,84,42,10) x common factors =1 x 588 = 588

LCM(49,84,42,10) = ( 49 × 84 × 42 × 10 ) / 588

LCM(49,84,42,10) = 1728720 / 588

LCM(49,84,42,10) = 2940
