Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 517/449,705/715
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 517,705
Greatest Common Factor of Numerators i.e. GCF of 517,705 is 47 .
LCM of Denominators means LCM of 449,715 as per the given fractions.
LCM of 449,715 is 321035 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 517,705
47 | 517, 705 |
11, 15 |
∴ So the GCF of the given numbers is 47 = 47

Factors of 705
List of positive integer factors of 705 that divides 705 without a remainder.
1,3,5,15,47,141,235,705
Greatest Common Factor
We found the factors 517,705 . The biggest common factor number is the GCF number.
So the greatest common factor 517,705 is 47.
Lets's calculate LCM of 449,715
Given numbers has no common factors except 1. So, there LCM is their product i.e 321035
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 47/321035
Therefore, the GCF of Fractions 517/449,705/715 is 47/321035
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 449,715 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(449,715) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(449,715) x common factors =1 x 1 = 1
LCM(449,715) = ( 449 × 715 ) / 1
LCM(449,715) = 321035 / 1
LCM(449,715) = 321035
Here are some samples of GCF of Fractions calculations.
