Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 40/817,18/8002
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 40,18
Greatest Common Factor of Numerators i.e. GCF of 40,18 is 2 .
LCM of Denominators means LCM of 817,8002 as per the given fractions.
LCM of 817,8002 is 6537634 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 40,18
2 | 40, 18 |
20, 9 |
∴ So the GCF of the given numbers is 2 = 2
Factors of 40
List of positive integer factors of 40 that divides 40 without a remainder.
1,2,4,5,8,10,20,40
Factors of 18
List of positive integer factors of 18 that divides 18 without a remainder.
1,2,3,6,9,18
Greatest Common Factor
We found the factors 40,18 . The biggest common factor number is the GCF number.
So the greatest common factor 40,18 is 2.
Lets's calculate LCM of 817,8002
Given numbers has no common factors except 1. So, there LCM is their product i.e 6537634
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/6537634
Therefore, the GCF of Fractions 40/817,18/8002 is 2/6537634
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 817,8002 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(817,8002) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(817,8002) x common factors =1 x 1 = 1
LCM(817,8002) = ( 817 × 8002 ) / 1
LCM(817,8002) = 6537634 / 1
LCM(817,8002) = 6537634
Here are some samples of GCF of Fractions calculations.
