Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 51/26,87/53,101/989
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 51,87,101
Greatest Common Factor of Numerators i.e. GCF of 51,87,101 is 1 .
LCM of Denominators means LCM of 26,53,989 as per the given fractions.
LCM of 26,53,989 is 1362842 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 51,87,101
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 51
List of positive integer factors of 51 that divides 51 without a remainder.
1,3,17,51
Factors of 87
List of positive integer factors of 87 that divides 87 without a remainder.
1,3,29,87
Factors of 101
List of positive integer factors of 101 that divides 101 without a remainder.
1,101
Greatest Common Factor
We found the factors 51,87,101 . The biggest common factor number is the GCF number.
So the greatest common factor 51,87,101 is 1.
Lets's calculate LCM of 26,53,989
Given numbers has no common factors except 1. So, there LCM is their product i.e 1362842
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1362842
Therefore, the GCF of Fractions 51/26,87/53,101/989 is 1/1362842
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 26,53,989 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(26,53,989) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(26,53,989) x common factors =1 x 1 = 1
LCM(26,53,989) = ( 26 × 53 × 989 ) / 1
LCM(26,53,989) = 1362842 / 1
LCM(26,53,989) = 1362842
Here are some samples of GCF of Fractions calculations.
