Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 470/20,8015/735
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 470,8015
Greatest Common Factor of Numerators i.e. GCF of 470,8015 is 5 .
LCM of Denominators means LCM of 20,735 as per the given fractions.
LCM of 20,735 is 2940 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 470,8015
5 | 470, 8015 |

1,5,7,35,229,1145,1603,8015
Greatest Common Factor
We found the factors 470,8015 . The biggest common factor number is the GCF number.
So the greatest common factor 470,8015 is 5.
Lets's calculate LCM of 20,735
5 | 20, 735 |
4, 147 |
∴ So the LCM of the given numbers is 5 x 4 x 147 = 2940
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/2940
Therefore, the GCF of Fractions 470/20,8015/735 is 5/2940
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 20,735 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(20,735) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(20,735) x common factors =5 x 1 = 5
LCM(20,735) = ( 20 × 735 ) / 5
LCM(20,735) = 14700 / 5
LCM(20,735) = 2940
