Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 157/512,769/208
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 157,769
Greatest Common Factor of Numerators i.e. GCF of 157,769 is 1 .
LCM of Denominators means LCM of 512,208 as per the given fractions.
LCM of 512,208 is 6656 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 157,769
∴ So GCF of numbers is 1 because of no common factors present between them.

1,157
Factors of 769
List of positive integer factors of 769 that divides 769 without a remainder.
1,769
Greatest Common Factor
We found the factors 157,769 . The biggest common factor number is the GCF number.
So the greatest common factor 157,769 is 1.
Lets's calculate LCM of 512,208
2 | 512, 208 |
2 | 256, 104 |
2 | 128, 52 |
2 | 64, 26 |
32, 13 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 32 x 13 = 6656
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/6656
Therefore, the GCF of Fractions 157/512,769/208 is 1/6656
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 512,208 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(512,208) = 16
common factors(in case of two or more numbers have common factors) = 1
GCF(512,208) x common factors =16 x 1 = 16
LCM(512,208) = ( 512 × 208 ) / 16
LCM(512,208) = 106496 / 16
LCM(512,208) = 6656
