Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 50/69,41/30,56/28,39/87
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 50,41,56,39
Greatest Common Factor of Numerators i.e. GCF of 50,41,56,39 is 1 .
LCM of Denominators means LCM of 69,30,28,87 as per the given fractions.
LCM of 69,30,28,87 is 280140 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 50,41,56,39
∴ So GCF of numbers is 1 because of no common factors present between them.

1,2,4,7,8,14,28,56
Factors of 39
List of positive integer factors of 39 that divides 39 without a remainder.
1,3,13,39
Greatest Common Factor
We found the factors 50,41,56,39 . The biggest common factor number is the GCF number.
So the greatest common factor 50,41,56,39 is 1.
Lets's calculate LCM of 69,30,28,87
2 | 69, 30, 28, 87 |
3 | 69, 15, 14, 87 |
23, 5, 14, 29 |
∴ So the LCM of the given numbers is 2 x 3 x 23 x 5 x 14 x 29 = 280140
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/280140
Therefore, the GCF of Fractions 50/69,41/30,56/28,39/87 is 1/280140
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 69,30,28,87 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(69,30,28,87) = 1
common factors(in case of two or more numbers have common factors) = 18
GCF(69,30,28,87) x common factors =1 x 18 = 18
LCM(69,30,28,87) = ( 69 × 30 × 28 × 87 ) / 18
LCM(69,30,28,87) = 5042520 / 18
LCM(69,30,28,87) = 280140
