Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 89/21,95/53,688/610
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 89,95,688
Greatest Common Factor of Numerators i.e. GCF of 89,95,688 is 1 .
LCM of Denominators means LCM of 21,53,610 as per the given fractions.
LCM of 21,53,610 is 678930 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 89,95,688
∴ So GCF of numbers is 1 because of no common factors present between them.

List of positive integer factors of 688 that divides 688 without a remainder.
1,2,4,8,16,43,86,172,344,688
Greatest Common Factor
We found the factors 89,95,688 . The biggest common factor number is the GCF number.
So the greatest common factor 89,95,688 is 1.
Lets's calculate LCM of 21,53,610
Given numbers has no common factors except 1. So, there LCM is their product i.e 678930
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/678930
Therefore, the GCF of Fractions 89/21,95/53,688/610 is 1/678930
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 21,53,610 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(21,53,610) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(21,53,610) x common factors =1 x 1 = 1
LCM(21,53,610) = ( 21 × 53 × 610 ) / 1
LCM(21,53,610) = 678930 / 1
LCM(21,53,610) = 678930
