Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 5/80,568/16,130/85
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 5,568,130
Greatest Common Factor of Numerators i.e. GCF of 5,568,130 is 1 .
LCM of Denominators means LCM of 80,16,85 as per the given fractions.
LCM of 80,16,85 is 1360 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 5,568,130
∴ So GCF of numbers is 1 because of no common factors present between them.

Greatest Common Factor
We found the factors 5,568,130 . The biggest common factor number is the GCF number.
So the greatest common factor 5,568,130 is 1.
Lets's calculate LCM of 80,16,85
2 | 80, 16, 85 |
2 | 40, 8, 85 |
2 | 20, 4, 85 |
2 | 10, 2, 85 |
5 | 5, 1, 85 |
1, 1, 17 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 5 x 1 x 1 x 17 = 1360
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1360
Therefore, the GCF of Fractions 5/80,568/16,130/85 is 1/1360
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 80,16,85 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(80,16,85) = 1
common factors(in case of two or more numbers have common factors) = 80
GCF(80,16,85) x common factors =1 x 80 = 80
LCM(80,16,85) = ( 80 × 16 × 85 ) / 80
LCM(80,16,85) = 108800 / 80
LCM(80,16,85) = 1360
