Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 39/15,79/56,791/511
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 39,79,791
Greatest Common Factor of Numerators i.e. GCF of 39,79,791 is 1 .
LCM of Denominators means LCM of 15,56,511 as per the given fractions.
LCM of 15,56,511 is 61320 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 39,79,791
∴ So GCF of numbers is 1 because of no common factors present between them.

1,79
Factors of 791
List of positive integer factors of 791 that divides 791 without a remainder.
1,7,113,791
Greatest Common Factor
We found the factors 39,79,791 . The biggest common factor number is the GCF number.
So the greatest common factor 39,79,791 is 1.
Lets's calculate LCM of 15,56,511
7 | 15, 56, 511 |
15, 8, 73 |
∴ So the LCM of the given numbers is 7 x 15 x 8 x 73 = 61320
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/61320
Therefore, the GCF of Fractions 39/15,79/56,791/511 is 1/61320
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 15,56,511 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(15,56,511) = 1
common factors(in case of two or more numbers have common factors) = 7
GCF(15,56,511) x common factors =1 x 7 = 7
LCM(15,56,511) = ( 15 × 56 × 511 ) / 7
LCM(15,56,511) = 429240 / 7
LCM(15,56,511) = 61320
