Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 711/56,491/4280
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 711,491
Greatest Common Factor of Numerators i.e. GCF of 711,491 is 1 .
LCM of Denominators means LCM of 56,4280 as per the given fractions.
LCM of 56,4280 is 29960 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 711,491
∴ So GCF of numbers is 1 because of no common factors present between them.

1,3,9,79,237,711
Factors of 491
List of positive integer factors of 491 that divides 491 without a remainder.
1,491
Greatest Common Factor
We found the factors 711,491 . The biggest common factor number is the GCF number.
So the greatest common factor 711,491 is 1.
Lets's calculate LCM of 56,4280
2 | 56, 4280 |
2 | 28, 2140 |
2 | 14, 1070 |
7, 535 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 7 x 535 = 29960
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/29960
Therefore, the GCF of Fractions 711/56,491/4280 is 1/29960
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 56,4280 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(56,4280) = 8
common factors(in case of two or more numbers have common factors) = 1
GCF(56,4280) x common factors =8 x 1 = 8
LCM(56,4280) = ( 56 × 4280 ) / 8
LCM(56,4280) = 239680 / 8
LCM(56,4280) = 29960
