Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 147/207,707/822
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 147,707
Greatest Common Factor of Numerators i.e. GCF of 147,707 is 7 .
LCM of Denominators means LCM of 207,822 as per the given fractions.
LCM of 207,822 is 56718 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 147,707
7 | 147, 707 |
21, 101 |
∴ So the GCF of the given numbers is 7 = 7

Greatest Common Factor
We found the factors 147,707 . The biggest common factor number is the GCF number.
So the greatest common factor 147,707 is 7.
Lets's calculate LCM of 207,822
3 | 207, 822 |
69, 274 |
∴ So the LCM of the given numbers is 3 x 69 x 274 = 56718
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/56718
Therefore, the GCF of Fractions 147/207,707/822 is 7/56718
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 207,822 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(207,822) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(207,822) x common factors =3 x 1 = 3
LCM(207,822) = ( 207 × 822 ) / 3
LCM(207,822) = 170154 / 3
LCM(207,822) = 56718
