Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 21/440,135/581
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 21,135
Greatest Common Factor of Numerators i.e. GCF of 21,135 is 3 .
LCM of Denominators means LCM of 440,581 as per the given fractions.
LCM of 440,581 is 255640 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 21,135
3 | 21, 135 |
7, 45 |
∴ So the GCF of the given numbers is 3 = 3
Factors of 21
List of positive integer factors of 21 that divides 21 without a remainder.
1,3,7,21
Factors of 135
List of positive integer factors of 135 that divides 135 without a remainder.
1,3,5,9,15,27,45,135
Greatest Common Factor
We found the factors 21,135 . The biggest common factor number is the GCF number.
So the greatest common factor 21,135 is 3.
Lets's calculate LCM of 440,581
Given numbers has no common factors except 1. So, there LCM is their product i.e 255640
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/255640
Therefore, the GCF of Fractions 21/440,135/581 is 3/255640
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 440,581 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(440,581) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(440,581) x common factors =1 x 1 = 1
LCM(440,581) = ( 440 × 581 ) / 1
LCM(440,581) = 255640 / 1
LCM(440,581) = 255640
Here are some samples of GCF of Fractions calculations.
