Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 432/57,450/686
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 432,450
Greatest Common Factor of Numerators i.e. GCF of 432,450 is 18 .
LCM of Denominators means LCM of 57,686 as per the given fractions.
LCM of 57,686 is 39102 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 432,450
2 | 432, 450 |
3 | 216, 225 |
3 | 72, 75 |
24, 25 |
∴ So the GCF of the given numbers is 2 x 3 x 3 = 18

1,2,3,5,6,9,10,15,18,25,30,45,50,75,90,150,225,450
Greatest Common Factor
We found the factors 432,450 . The biggest common factor number is the GCF number.
So the greatest common factor 432,450 is 18.
Lets's calculate LCM of 57,686
Given numbers has no common factors except 1. So, there LCM is their product i.e 39102
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 18/39102
Therefore, the GCF of Fractions 432/57,450/686 is 18/39102
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 57,686 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(57,686) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(57,686) x common factors =1 x 1 = 1
LCM(57,686) = ( 57 × 686 ) / 1
LCM(57,686) = 39102 / 1
LCM(57,686) = 39102
