Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 75/24,10/35,31/72,74/715
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 75,10,31,74
Greatest Common Factor of Numerators i.e. GCF of 75,10,31,74 is 1 .
LCM of Denominators means LCM of 24,35,72,715 as per the given fractions.
LCM of 24,35,72,715 is 360360 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 75,10,31,74
∴ So GCF of numbers is 1 because of no common factors present between them.

1,31
Factors of 74
List of positive integer factors of 74 that divides 74 without a remainder.
1,2,37,74
Greatest Common Factor
We found the factors 75,10,31,74 . The biggest common factor number is the GCF number.
So the greatest common factor 75,10,31,74 is 1.
Lets's calculate LCM of 24,35,72,715
2 | 24, 35, 72, 715 |
2 | 12, 35, 36, 715 |
2 | 6, 35, 18, 715 |
3 | 3, 35, 9, 715 |
5 | 1, 35, 3, 715 |
1, 7, 3, 143 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 3 x 5 x 1 x 7 x 3 x 143 = 360360
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/360360
Therefore, the GCF of Fractions 75/24,10/35,31/72,74/715 is 1/360360
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 24,35,72,715 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(24,35,72,715) = 1
common factors(in case of two or more numbers have common factors) = 120
GCF(24,35,72,715) x common factors =1 x 120 = 120
LCM(24,35,72,715) = ( 24 × 35 × 72 × 715 ) / 120
LCM(24,35,72,715) = 43243200 / 120
LCM(24,35,72,715) = 360360
