Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 35/15,20/34,48/35,90/21
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 35,20,48,90
Greatest Common Factor of Numerators i.e. GCF of 35,20,48,90 is 1 .
LCM of Denominators means LCM of 15,34,35,21 as per the given fractions.
LCM of 15,34,35,21 is 3570 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 35,20,48,90
∴ So GCF of numbers is 1 because of no common factors present between them.

List of positive integer factors of 90 that divides 90 without a remainder.
1,2,3,5,6,9,10,15,18,30,45,90
Greatest Common Factor
We found the factors 35,20,48,90 . The biggest common factor number is the GCF number.
So the greatest common factor 35,20,48,90 is 1.
Lets's calculate LCM of 15,34,35,21
3 | 15, 34, 35, 21 |
5 | 5, 34, 35, 7 |
7 | 1, 34, 7, 7 |
1, 34, 1, 1 |
∴ So the LCM of the given numbers is 3 x 5 x 7 x 1 x 34 x 1 x 1 = 3570
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/3570
Therefore, the GCF of Fractions 35/15,20/34,48/35,90/21 is 1/3570
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 15,34,35,21 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(15,34,35,21) = 1
common factors(in case of two or more numbers have common factors) = 105
GCF(15,34,35,21) x common factors =1 x 105 = 105
LCM(15,34,35,21) = ( 15 × 34 × 35 × 21 ) / 105
LCM(15,34,35,21) = 374850 / 105
LCM(15,34,35,21) = 3570
