Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 12/28,49/49,22/21,35/27
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 12,49,22,35
Greatest Common Factor of Numerators i.e. GCF of 12,49,22,35 is 1 .
LCM of Denominators means LCM of 28,49,21,27 as per the given fractions.
LCM of 28,49,21,27 is 5292 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 12,49,22,35
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 12
List of positive integer factors of 12 that divides 12 without a remainder.
1,2,3,4,6,12
Factors of 49

1,7,49
Factors of 22
List of positive integer factors of 22 that divides 22 without a remainder.
1,2,11,22
Factors of 35
List of positive integer factors of 35 that divides 35 without a remainder.
1,5,7,35
Greatest Common Factor
We found the factors 12,49,22,35 . The biggest common factor number is the GCF number.
So the greatest common factor 12,49,22,35 is 1.
Lets's calculate LCM of 28,49,21,27
3 | 28, 49, 21, 27 |
7 | 28, 49, 7, 9 |
4, 1, 7, 9 |
∴ So the LCM of the given numbers is 3 x 7 x 4 x 1 x 7 x 9 = 5292
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/5292
Therefore, the GCF of Fractions 12/28,49/49,22/21,35/27 is 1/5292
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 28,49,21,27 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(28,49,21,27) = 1
common factors(in case of two or more numbers have common factors) = 147
GCF(28,49,21,27) x common factors =1 x 147 = 147
LCM(28,49,21,27) = ( 28 × 49 × 21 × 27 ) / 147
LCM(28,49,21,27) = 777924 / 147
LCM(28,49,21,27) = 5292
