Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 69/19,70/61,990/907
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 69,70,990
Greatest Common Factor of Numerators i.e. GCF of 69,70,990 is 1 .
LCM of Denominators means LCM of 19,61,907 as per the given fractions.
LCM of 19,61,907 is 1051213 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 69,70,990
∴ So GCF of numbers is 1 because of no common factors present between them.

List of positive integer factors of 70 that divides 70 without a remainder.
1,2,5,7,10,14,35,70
Factors of 990
List of positive integer factors of 990 that divides 990 without a remainder.
1,2,3,5,6,9,10,11,15,18,22,30,33,45,55,66,90,99,110,165,198,330,495,990
Greatest Common Factor
We found the factors 69,70,990 . The biggest common factor number is the GCF number.
So the greatest common factor 69,70,990 is 1.
Lets's calculate LCM of 19,61,907
Given numbers has no common factors except 1. So, there LCM is their product i.e 1051213
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1051213
Therefore, the GCF of Fractions 69/19,70/61,990/907 is 1/1051213
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 19,61,907 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(19,61,907) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(19,61,907) x common factors =1 x 1 = 1
LCM(19,61,907) = ( 19 × 61 × 907 ) / 1
LCM(19,61,907) = 1051213 / 1
LCM(19,61,907) = 1051213
Here are some samples of GCF of Fractions calculations.
