Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 76/56,55/70,659/58
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 76,55,659
Greatest Common Factor of Numerators i.e. GCF of 76,55,659 is 1 .
LCM of Denominators means LCM of 56,70,58 as per the given fractions.
LCM of 56,70,58 is 8120 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 76,55,659
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 76

1,5,11,55
Factors of 659
List of positive integer factors of 659 that divides 659 without a remainder.
1,659
Greatest Common Factor
We found the factors 76,55,659 . The biggest common factor number is the GCF number.
So the greatest common factor 76,55,659 is 1.
Lets's calculate LCM of 56,70,58
2 | 56, 70, 58 |
7 | 28, 35, 29 |
4, 5, 29 |
∴ So the LCM of the given numbers is 2 x 7 x 4 x 5 x 29 = 8120
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/8120
Therefore, the GCF of Fractions 76/56,55/70,659/58 is 1/8120
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 56,70,58 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(56,70,58) = 2
common factors(in case of two or more numbers have common factors) = 14
GCF(56,70,58) x common factors =2 x 14 = 28
LCM(56,70,58) = ( 56 × 70 × 58 ) / 28
LCM(56,70,58) = 227360 / 28
LCM(56,70,58) = 8120
