Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 705/402,195/124
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 705,195
Greatest Common Factor of Numerators i.e. GCF of 705,195 is 15 .
LCM of Denominators means LCM of 402,124 as per the given fractions.
LCM of 402,124 is 24924 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 705,195
3 | 705, 195 |
5 | 235, 65 |
47, 13 |
∴ So the GCF of the given numbers is 3 x 5 = 15

1,3,5,13,15,39,65,195
Greatest Common Factor
We found the factors 705,195 . The biggest common factor number is the GCF number.
So the greatest common factor 705,195 is 15.
Lets's calculate LCM of 402,124
2 | 402, 124 |
201, 62 |
∴ So the LCM of the given numbers is 2 x 201 x 62 = 24924
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 15/24924
Therefore, the GCF of Fractions 705/402,195/124 is 15/24924
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 402,124 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(402,124) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(402,124) x common factors =2 x 1 = 2
LCM(402,124) = ( 402 × 124 ) / 2
LCM(402,124) = 49848 / 2
LCM(402,124) = 24924
