Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 172/42,9717/384
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 172,9717
Greatest Common Factor of Numerators i.e. GCF of 172,9717 is 1 .
LCM of Denominators means LCM of 42,384 as per the given fractions.
LCM of 42,384 is 2688 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 172,9717
∴ So GCF of numbers is 1 because of no common factors present between them.

1,2,4,43,86,172
Factors of 9717
List of positive integer factors of 9717 that divides 9717 without a remainder.
1,3,41,79,123,237,3239,9717
Greatest Common Factor
We found the factors 172,9717 . The biggest common factor number is the GCF number.
So the greatest common factor 172,9717 is 1.
Lets's calculate LCM of 42,384
2 | 42, 384 |
3 | 21, 192 |
7, 64 |
∴ So the LCM of the given numbers is 2 x 3 x 7 x 64 = 2688
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2688
Therefore, the GCF of Fractions 172/42,9717/384 is 1/2688
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 42,384 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(42,384) = 6
common factors(in case of two or more numbers have common factors) = 1
GCF(42,384) x common factors =6 x 1 = 6
LCM(42,384) = ( 42 × 384 ) / 6
LCM(42,384) = 16128 / 6
LCM(42,384) = 2688
