Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 21/44,57/29,690/613
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 21,57,690
Greatest Common Factor of Numerators i.e. GCF of 21,57,690 is 3 .
LCM of Denominators means LCM of 44,29,613 as per the given fractions.
LCM of 44,29,613 is 782188 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 21,57,690
3 | 21, 57, 690 |
7, 19, 230 |
∴ So the GCF of the given numbers is 3 = 3

List of positive integer factors of 21 that divides 21 without a remainder.
1,3,7,21
Factors of 57
List of positive integer factors of 57 that divides 57 without a remainder.
1,3,19,57
Factors of 690
List of positive integer factors of 690 that divides 690 without a remainder.
1,2,3,5,6,10,15,23,30,46,69,115,138,230,345,690
Greatest Common Factor
We found the factors 21,57,690 . The biggest common factor number is the GCF number.
So the greatest common factor 21,57,690 is 3.
Lets's calculate LCM of 44,29,613
Given numbers has no common factors except 1. So, there LCM is their product i.e 782188
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/782188
Therefore, the GCF of Fractions 21/44,57/29,690/613 is 3/782188
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 44,29,613 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(44,29,613) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(44,29,613) x common factors =1 x 1 = 1
LCM(44,29,613) = ( 44 × 29 × 613 ) / 1
LCM(44,29,613) = 782188 / 1
LCM(44,29,613) = 782188
