Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 75/839,285/543
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 75,285
Greatest Common Factor of Numerators i.e. GCF of 75,285 is 15 .
LCM of Denominators means LCM of 839,543 as per the given fractions.
LCM of 839,543 is 455577 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 75,285
3 | 75, 285 |
5 | 25, 95 |
5, 19 |
∴ So the GCF of the given numbers is 3 x 5 = 15
Factors of 75
List of positive integer factors of 75 that divides 75 without a remainder.
1,3,5,15,25,75
Factors of 285
List of positive integer factors of 285 that divides 285 without a remainder.
1,3,5,15,19,57,95,285
Greatest Common Factor
We found the factors 75,285 . The biggest common factor number is the GCF number.
So the greatest common factor 75,285 is 15.
Lets's calculate LCM of 839,543
Given numbers has no common factors except 1. So, there LCM is their product i.e 455577
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 15/455577
Therefore, the GCF of Fractions 75/839,285/543 is 15/455577
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 839,543 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(839,543) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(839,543) x common factors =1 x 1 = 1
LCM(839,543) = ( 839 × 543 ) / 1
LCM(839,543) = 455577 / 1
LCM(839,543) = 455577
Here are some samples of GCF of Fractions calculations.
