Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 130/980,231/440
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 130,231
Greatest Common Factor of Numerators i.e. GCF of 130,231 is 1 .
LCM of Denominators means LCM of 980,440 as per the given fractions.
LCM of 980,440 is 21560 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 130,231
∴ So GCF of numbers is 1 because of no common factors present between them.

1,2,5,10,13,26,65,130
Factors of 231
List of positive integer factors of 231 that divides 231 without a remainder.
1,3,7,11,21,33,77,231
Greatest Common Factor
We found the factors 130,231 . The biggest common factor number is the GCF number.
So the greatest common factor 130,231 is 1.
Lets's calculate LCM of 980,440
2 | 980, 440 |
2 | 490, 220 |
5 | 245, 110 |
49, 22 |
∴ So the LCM of the given numbers is 2 x 2 x 5 x 49 x 22 = 21560
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/21560
Therefore, the GCF of Fractions 130/980,231/440 is 1/21560
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 980,440 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(980,440) = 20
common factors(in case of two or more numbers have common factors) = 1
GCF(980,440) x common factors =20 x 1 = 20
LCM(980,440) = ( 980 × 440 ) / 20
LCM(980,440) = 431200 / 20
LCM(980,440) = 21560
