Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 109/128,315/152
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 109,315
Greatest Common Factor of Numerators i.e. GCF of 109,315 is 1 .
LCM of Denominators means LCM of 128,152 as per the given fractions.
LCM of 128,152 is 2432 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 109,315
∴ So GCF of numbers is 1 because of no common factors present between them.

1,109
Factors of 315
List of positive integer factors of 315 that divides 315 without a remainder.
1,3,5,7,9,15,21,35,45,63,105,315
Greatest Common Factor
We found the factors 109,315 . The biggest common factor number is the GCF number.
So the greatest common factor 109,315 is 1.
Lets's calculate LCM of 128,152
2 | 128, 152 |
2 | 64, 76 |
2 | 32, 38 |
16, 19 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 16 x 19 = 2432
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2432
Therefore, the GCF of Fractions 109/128,315/152 is 1/2432
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 128,152 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(128,152) = 8
common factors(in case of two or more numbers have common factors) = 1
GCF(128,152) x common factors =8 x 1 = 8
LCM(128,152) = ( 128 × 152 ) / 8
LCM(128,152) = 19456 / 8
LCM(128,152) = 2432
