Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 399/683,987/414
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 399,987
Greatest Common Factor of Numerators i.e. GCF of 399,987 is 21 .
LCM of Denominators means LCM of 683,414 as per the given fractions.
LCM of 683,414 is 282762 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 399,987
3 | 399, 987 |
7 | 133, 329 |
19, 47 |
∴ So the GCF of the given numbers is 3 x 7 = 21

Factors of 987
List of positive integer factors of 987 that divides 987 without a remainder.
1,3,7,21,47,141,329,987
Greatest Common Factor
We found the factors 399,987 . The biggest common factor number is the GCF number.
So the greatest common factor 399,987 is 21.
Lets's calculate LCM of 683,414
Given numbers has no common factors except 1. So, there LCM is their product i.e 282762
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 21/282762
Therefore, the GCF of Fractions 399/683,987/414 is 21/282762
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 683,414 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(683,414) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(683,414) x common factors =1 x 1 = 1
LCM(683,414) = ( 683 × 414 ) / 1
LCM(683,414) = 282762 / 1
LCM(683,414) = 282762
Here are some samples of GCF of Fractions calculations.
