Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 21/372,210/637
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 21,210
Greatest Common Factor of Numerators i.e. GCF of 21,210 is 21 .
LCM of Denominators means LCM of 372,637 as per the given fractions.
LCM of 372,637 is 236964 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 21,210
3 | 21, 210 |
7 | 7, 70 |
1, 10 |
∴ So the GCF of the given numbers is 3 x 7 = 21
Factors of 21
List of positive integer factors of 21 that divides 21 without a remainder.
1,3,7,21
Factors of 210
List of positive integer factors of 210 that divides 210 without a remainder.
1,2,3,5,6,7,10,14,15,21,30,35,42,70,105,210
Greatest Common Factor
We found the factors 21,210 . The biggest common factor number is the GCF number.
So the greatest common factor 21,210 is 21.
Lets's calculate LCM of 372,637
Given numbers has no common factors except 1. So, there LCM is their product i.e 236964
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 21/236964
Therefore, the GCF of Fractions 21/372,210/637 is 21/236964
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 372,637 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(372,637) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(372,637) x common factors =1 x 1 = 1
LCM(372,637) = ( 372 × 637 ) / 1
LCM(372,637) = 236964 / 1
LCM(372,637) = 236964
Here are some samples of GCF of Fractions calculations.
