Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 7/17,9/89,20/53,21/714
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 7,9,20,21
Greatest Common Factor of Numerators i.e. GCF of 7,9,20,21 is 1 .
LCM of Denominators means LCM of 17,89,53,714 as per the given fractions.
LCM of 17,89,53,714 is 3367938 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 7,9,20,21
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 7
List of positive integer factors of 7 that divides 7 without a remainder.
1,7

1,3,9
Factors of 20
List of positive integer factors of 20 that divides 20 without a remainder.
1,2,4,5,10,20
Factors of 21
List of positive integer factors of 21 that divides 21 without a remainder.
1,3,7,21
Greatest Common Factor
We found the factors 7,9,20,21 . The biggest common factor number is the GCF number.
So the greatest common factor 7,9,20,21 is 1.
Lets's calculate LCM of 17,89,53,714
17 | 17, 89, 53, 714 |
1, 89, 53, 42 |
∴ So the LCM of the given numbers is 17 x 1 x 89 x 53 x 42 = 3367938
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/3367938
Therefore, the GCF of Fractions 7/17,9/89,20/53,21/714 is 1/3367938
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 17,89,53,714 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(17,89,53,714) = 1
common factors(in case of two or more numbers have common factors) = 17
GCF(17,89,53,714) x common factors =1 x 17 = 17
LCM(17,89,53,714) = ( 17 × 89 × 53 × 714 ) / 17
LCM(17,89,53,714) = 57254946 / 17
LCM(17,89,53,714) = 3367938
