Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 222/250,1391/780
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 222,1391
Greatest Common Factor of Numerators i.e. GCF of 222,1391 is 1 .
LCM of Denominators means LCM of 250,780 as per the given fractions.
LCM of 250,780 is 19500 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 222,1391
∴ So GCF of numbers is 1 because of no common factors present between them.

List of positive integer factors of 222 that divides 222 without a remainder.
1,2,3,6,37,74,111,222
Factors of 1391
List of positive integer factors of 1391 that divides 1391 without a remainder.
1,13,107,1391
Greatest Common Factor
We found the factors 222,1391 . The biggest common factor number is the GCF number.
So the greatest common factor 222,1391 is 1.
Lets's calculate LCM of 250,780
2 | 250, 780 |
5 | 125, 390 |
25, 78 |
∴ So the LCM of the given numbers is 2 x 5 x 25 x 78 = 19500
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/19500
Therefore, the GCF of Fractions 222/250,1391/780 is 1/19500
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 250,780 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(250,780) = 10
common factors(in case of two or more numbers have common factors) = 1
GCF(250,780) x common factors =10 x 1 = 10
LCM(250,780) = ( 250 × 780 ) / 10
LCM(250,780) = 195000 / 10
LCM(250,780) = 19500
