Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 16/14,39/42,25/78,82/39
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 16,39,25,82
Greatest Common Factor of Numerators i.e. GCF of 16,39,25,82 is 1 .
LCM of Denominators means LCM of 14,42,78,39 as per the given fractions.
LCM of 14,42,78,39 is 546 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 16,39,25,82
∴ So GCF of numbers is 1 because of no common factors present between them.

1,3,13,39
Factors of 25
List of positive integer factors of 25 that divides 25 without a remainder.
1,5,25
Factors of 82
List of positive integer factors of 82 that divides 82 without a remainder.
1,2,41,82
Greatest Common Factor
We found the factors 16,39,25,82 . The biggest common factor number is the GCF number.
So the greatest common factor 16,39,25,82 is 1.
Lets's calculate LCM of 14,42,78,39
2 | 14, 42, 78, 39 |
3 | 7, 21, 39, 39 |
7 | 7, 7, 13, 13 |
13 | 1, 1, 13, 13 |
1, 1, 1, 1 |
∴ So the LCM of the given numbers is 2 x 3 x 7 x 13 x 1 x 1 x 1 x 1 = 546
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/546
Therefore, the GCF of Fractions 16/14,39/42,25/78,82/39 is 1/546
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 14,42,78,39 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(14,42,78,39) = 1
common factors(in case of two or more numbers have common factors) = 3276
GCF(14,42,78,39) x common factors =1 x 3276 = 3276
LCM(14,42,78,39) = ( 14 × 42 × 78 × 39 ) / 3276
LCM(14,42,78,39) = 1788696 / 3276
LCM(14,42,78,39) = 546
