Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 90/45,150/75,225/225
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 90,150,225
Greatest Common Factor of Numerators i.e. GCF of 90,150,225 is 15 .
LCM of Denominators means LCM of 45,75,225 as per the given fractions.
LCM of 45,75,225 is 225 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 90,150,225
3 | 90, 150, 225 |
5 | 30, 50, 75 |

Greatest Common Factor
We found the factors 90,150,225 . The biggest common factor number is the GCF number.
So the greatest common factor 90,150,225 is 15.
Lets's calculate LCM of 45,75,225
3 | 45, 75, 225 |
3 | 15, 25, 75 |
5 | 5, 25, 25 |
5 | 1, 5, 5 |
1, 1, 1 |
∴ So the LCM of the given numbers is 3 x 3 x 5 x 5 x 1 x 1 x 1 = 225
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 15/225
Therefore, the GCF of Fractions 90/45,150/75,225/225 is 15/225
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 45,75,225 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(45,75,225) = 15
common factors(in case of two or more numbers have common factors) = 225
GCF(45,75,225) x common factors =15 x 225 = 3375
LCM(45,75,225) = ( 45 × 75 × 225 ) / 3375
LCM(45,75,225) = 759375 / 3375
LCM(45,75,225) = 225
