Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 8/56,19/88,53/12,70/12
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 8,19,53,70
Greatest Common Factor of Numerators i.e. GCF of 8,19,53,70 is 1 .
LCM of Denominators means LCM of 56,88,12,12 as per the given fractions.
LCM of 56,88,12,12 is 1848 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 8,19,53,70
∴ So GCF of numbers is 1 because of no common factors present between them.

List of positive integer factors of 70 that divides 70 without a remainder.
1,2,5,7,10,14,35,70
Greatest Common Factor
We found the factors 8,19,53,70 . The biggest common factor number is the GCF number.
So the greatest common factor 8,19,53,70 is 1.
Lets's calculate LCM of 56,88,12,12
2 | 56, 88, 12, 12 |
2 | 28, 44, 6, 6 |
2 | 14, 22, 3, 3 |
3 | 7, 11, 3, 3 |
7, 11, 1, 1 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 3 x 7 x 11 x 1 x 1 = 1848
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1848
Therefore, the GCF of Fractions 8/56,19/88,53/12,70/12 is 1/1848
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 56,88,12,12 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(56,88,12,12) = 4
common factors(in case of two or more numbers have common factors) = 96
GCF(56,88,12,12) x common factors =4 x 96 = 384
LCM(56,88,12,12) = ( 56 × 88 × 12 × 12 ) / 384
LCM(56,88,12,12) = 709632 / 384
LCM(56,88,12,12) = 1848
