Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 88/16,20/18,257/98
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 88,20,257
Greatest Common Factor of Numerators i.e. GCF of 88,20,257 is 1 .
LCM of Denominators means LCM of 16,18,98 as per the given fractions.
LCM of 16,18,98 is 7056 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 88,20,257
∴ So GCF of numbers is 1 because of no common factors present between them.

Factors of 257
List of positive integer factors of 257 that divides 257 without a remainder.
1,257
Greatest Common Factor
We found the factors 88,20,257 . The biggest common factor number is the GCF number.
So the greatest common factor 88,20,257 is 1.
Lets's calculate LCM of 16,18,98
2 | 16, 18, 98 |
8, 9, 49 |
∴ So the LCM of the given numbers is 2 x 8 x 9 x 49 = 7056
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/7056
Therefore, the GCF of Fractions 88/16,20/18,257/98 is 1/7056
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 16,18,98 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(16,18,98) = 2
common factors(in case of two or more numbers have common factors) = 2
GCF(16,18,98) x common factors =2 x 2 = 4
LCM(16,18,98) = ( 16 × 18 × 98 ) / 4
LCM(16,18,98) = 28224 / 4
LCM(16,18,98) = 7056
