Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 656/89,368/649
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 656,368
Greatest Common Factor of Numerators i.e. GCF of 656,368 is 16 .
LCM of Denominators means LCM of 89,649 as per the given fractions.
LCM of 89,649 is 57761 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 656,368
2 | 656, 368 |
2 | 328, 184 |
2 | 164, 92 |
2 | 82, 46 |
41, 23 |
∴ So the GCF of the given numbers is 2 x 2 x 2 x 2 = 16

1,2,4,8,16,23,46,92,184,368
Greatest Common Factor
We found the factors 656,368 . The biggest common factor number is the GCF number.
So the greatest common factor 656,368 is 16.
Lets's calculate LCM of 89,649
Given numbers has no common factors except 1. So, there LCM is their product i.e 57761
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 16/57761
Therefore, the GCF of Fractions 656/89,368/649 is 16/57761
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 89,649 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(89,649) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(89,649) x common factors =1 x 1 = 1
LCM(89,649) = ( 89 × 649 ) / 1
LCM(89,649) = 57761 / 1
LCM(89,649) = 57761
