Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 21/69,58/50,790/290
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 21,58,790
Greatest Common Factor of Numerators i.e. GCF of 21,58,790 is 1 .
LCM of Denominators means LCM of 69,50,290 as per the given fractions.
LCM of 69,50,290 is 100050 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 21,58,790
∴ So GCF of numbers is 1 because of no common factors present between them.

1,3,7,21
Factors of 58
List of positive integer factors of 58 that divides 58 without a remainder.
1,2,29,58
Factors of 790
List of positive integer factors of 790 that divides 790 without a remainder.
1,2,5,10,79,158,395,790
Greatest Common Factor
We found the factors 21,58,790 . The biggest common factor number is the GCF number.
So the greatest common factor 21,58,790 is 1.
Lets's calculate LCM of 69,50,290
2 | 69, 50, 290 |
5 | 69, 25, 145 |
69, 5, 29 |
∴ So the LCM of the given numbers is 2 x 5 x 69 x 5 x 29 = 100050
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/100050
Therefore, the GCF of Fractions 21/69,58/50,790/290 is 1/100050
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 69,50,290 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(69,50,290) = 1
common factors(in case of two or more numbers have common factors) = 10
GCF(69,50,290) x common factors =1 x 10 = 10
LCM(69,50,290) = ( 69 × 50 × 290 ) / 10
LCM(69,50,290) = 1000500 / 10
LCM(69,50,290) = 100050
