Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 75/23,96/70,970/805
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 75,96,970
Greatest Common Factor of Numerators i.e. GCF of 75,96,970 is 1 .
LCM of Denominators means LCM of 23,70,805 as per the given fractions.
LCM of 23,70,805 is 1610 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 75,96,970
∴ So GCF of numbers is 1 because of no common factors present between them.

List of positive integer factors of 75 that divides 75 without a remainder.
1,3,5,15,25,75
Factors of 96
List of positive integer factors of 96 that divides 96 without a remainder.
1,2,3,4,6,8,12,16,24,32,48,96
Factors of 970
List of positive integer factors of 970 that divides 970 without a remainder.
1,2,5,10,97,194,485,970
Greatest Common Factor
We found the factors 75,96,970 . The biggest common factor number is the GCF number.
So the greatest common factor 75,96,970 is 1.
Lets's calculate LCM of 23,70,805
5 | 23, 70, 805 |
7 | 23, 14, 161 |
23 | 23, 2, 23 |
1, 2, 1 |
∴ So the LCM of the given numbers is 5 x 7 x 23 x 1 x 2 x 1 = 1610
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1610
Therefore, the GCF of Fractions 75/23,96/70,970/805 is 1/1610
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 23,70,805 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(23,70,805) = 1
common factors(in case of two or more numbers have common factors) = 805
GCF(23,70,805) x common factors =1 x 805 = 805
LCM(23,70,805) = ( 23 × 70 × 805 ) / 805
LCM(23,70,805) = 1296050 / 805
LCM(23,70,805) = 1610
