Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 78/586,738/645
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 78,738
Greatest Common Factor of Numerators i.e. GCF of 78,738 is 6 .
LCM of Denominators means LCM of 586,645 as per the given fractions.
LCM of 586,645 is 377970 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 78,738
2 | 78, 738 |
3 | 39, 369 |
13, 123 |
∴ So the GCF of the given numbers is 2 x 3 = 6

List of positive integer factors of 738 that divides 738 without a remainder.
1,2,3,6,9,18,41,82,123,246,369,738
Greatest Common Factor
We found the factors 78,738 . The biggest common factor number is the GCF number.
So the greatest common factor 78,738 is 6.
Lets's calculate LCM of 586,645
Given numbers has no common factors except 1. So, there LCM is their product i.e 377970
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 6/377970
Therefore, the GCF of Fractions 78/586,738/645 is 6/377970
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 586,645 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(586,645) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(586,645) x common factors =1 x 1 = 1
LCM(586,645) = ( 586 × 645 ) / 1
LCM(586,645) = 377970 / 1
LCM(586,645) = 377970
