Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 239/628,1123/612
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 239,1123
Greatest Common Factor of Numerators i.e. GCF of 239,1123 is 1 .
LCM of Denominators means LCM of 628,612 as per the given fractions.
LCM of 628,612 is 96084 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 239,1123
∴ So GCF of numbers is 1 because of no common factors present between them.

Factors of 1123
List of positive integer factors of 1123 that divides 1123 without a remainder.
1,1123
Greatest Common Factor
We found the factors 239,1123 . The biggest common factor number is the GCF number.
So the greatest common factor 239,1123 is 1.
Lets's calculate LCM of 628,612
2 | 628, 612 |
2 | 314, 306 |
157, 153 |
∴ So the LCM of the given numbers is 2 x 2 x 157 x 153 = 96084
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/96084
Therefore, the GCF of Fractions 239/628,1123/612 is 1/96084
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 628,612 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(628,612) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(628,612) x common factors =4 x 1 = 4
LCM(628,612) = ( 628 × 612 ) / 4
LCM(628,612) = 384336 / 4
LCM(628,612) = 96084
