Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 3/47,7/22,38/10,35/981
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 3,7,38,35
Greatest Common Factor of Numerators i.e. GCF of 3,7,38,35 is 1 .
LCM of Denominators means LCM of 47,22,10,981 as per the given fractions.
LCM of 47,22,10,981 is 5071770 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 3,7,38,35
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 3
List of positive integer factors of 3 that divides 3 without a remainder.
1,3

1,7
Factors of 38
List of positive integer factors of 38 that divides 38 without a remainder.
1,2,19,38
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 3,7,38,35 . The biggest common factor number is the GCF number.
So the greatest common factor 3,7,38,35 is 1.
Lets's calculate LCM of 47,22,10,981
2 | 47, 22, 10, 981 |
47, 11, 5, 981 |
∴ So the LCM of the given numbers is 2 x 47 x 11 x 5 x 981 = 5071770
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/5071770
Therefore, the GCF of Fractions 3/47,7/22,38/10,35/981 is 1/5071770
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 47,22,10,981 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(47,22,10,981) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(47,22,10,981) x common factors =1 x 2 = 2
LCM(47,22,10,981) = ( 47 × 22 × 10 × 981 ) / 2
LCM(47,22,10,981) = 10143540 / 2
LCM(47,22,10,981) = 5071770
