Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 400/97,224/2305
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 400,224
Greatest Common Factor of Numerators i.e. GCF of 400,224 is 16 .
LCM of Denominators means LCM of 97,2305 as per the given fractions.
LCM of 97,2305 is 223585 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 400,224
2 | 400, 224 |
2 | 200, 112 |
2 | 100, 56 |
2 | 50, 28 |
25, 14 |
∴ So the GCF of the given numbers is 2 x 2 x 2 x 2 = 16

1,2,4,7,8,14,16,28,32,56,112,224
Greatest Common Factor
We found the factors 400,224 . The biggest common factor number is the GCF number.
So the greatest common factor 400,224 is 16.
Lets's calculate LCM of 97,2305
Given numbers has no common factors except 1. So, there LCM is their product i.e 223585
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 16/223585
Therefore, the GCF of Fractions 400/97,224/2305 is 16/223585
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 97,2305 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(97,2305) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(97,2305) x common factors =1 x 1 = 1
LCM(97,2305) = ( 97 × 2305 ) / 1
LCM(97,2305) = 223585 / 1
LCM(97,2305) = 223585
Here are some samples of GCF of Fractions calculations.
