Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 40/405,760/403
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 40,760
Greatest Common Factor of Numerators i.e. GCF of 40,760 is 40 .
LCM of Denominators means LCM of 405,403 as per the given fractions.
LCM of 405,403 is 163215 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 40,760
2 | 40, 760 |
2 | 20, 380 |
2 | 10, 190 |
5 | 5, 95 |
1, 19 |
∴ So the GCF of the given numbers is 2 x 2 x 2 x 5 = 40

1,2,4,5,8,10,20,40
Factors of 760
List of positive integer factors of 760 that divides 760 without a remainder.
1,2,4,5,8,10,19,20,38,40,76,95,152,190,380,760
Greatest Common Factor
We found the factors 40,760 . The biggest common factor number is the GCF number.
So the greatest common factor 40,760 is 40.
Lets's calculate LCM of 405,403
Given numbers has no common factors except 1. So, there LCM is their product i.e 163215
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 40/163215
Therefore, the GCF of Fractions 40/405,760/403 is 40/163215
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 405,403 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(405,403) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(405,403) x common factors =1 x 1 = 1
LCM(405,403) = ( 405 × 403 ) / 1
LCM(405,403) = 163215 / 1
LCM(405,403) = 163215
Here are some samples of GCF of Fractions calculations.
