Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 64/47,52/10,20/538
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 64,52,20
Greatest Common Factor of Numerators i.e. GCF of 64,52,20 is 4 .
LCM of Denominators means LCM of 47,10,538 as per the given fractions.
LCM of 47,10,538 is 126430 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 64,52,20
2 | 64, 52, 20 |
2 | 32, 26, 10 |
16, 13, 5 |
∴ So the GCF of the given numbers is 2 x 2 = 4
Factors of 64
List of positive integer factors of 64 that divides 64 without a remainder.
1,2,4,8,16,32,64
Factors of 52

1,2,4,13,26,52
Factors of 20
List of positive integer factors of 20 that divides 20 without a remainder.
1,2,4,5,10,20
Greatest Common Factor
We found the factors 64,52,20 . The biggest common factor number is the GCF number.
So the greatest common factor 64,52,20 is 4.
Lets's calculate LCM of 47,10,538
2 | 47, 10, 538 |
47, 5, 269 |
∴ So the LCM of the given numbers is 2 x 47 x 5 x 269 = 126430
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/126430
Therefore, the GCF of Fractions 64/47,52/10,20/538 is 4/126430
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 47,10,538 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(47,10,538) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(47,10,538) x common factors =1 x 2 = 2
LCM(47,10,538) = ( 47 × 10 × 538 ) / 2
LCM(47,10,538) = 252860 / 2
LCM(47,10,538) = 126430
