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 28,392
Greatest Common Factor of Numerators i.e. GCF of 28,392 is 28 .
LCM of Denominators means LCM of 492,886 as per the given fractions.
LCM of 492,886 is 217956 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 28,392
2 | 28, 392 |
2 | 14, 196 |
7 | 7, 98 |
1, 14 |
∴ So the GCF of the given numbers is 2 x 2 x 7 = 28

1,2,4,7,14,28
Factors of 392
List of positive integer factors of 392 that divides 392 without a remainder.
1,2,4,7,8,14,28,49,56,98,196,392
Greatest Common Factor
We found the factors 28,392 . The biggest common factor number is the GCF number.
So the greatest common factor 28,392 is 28.
Lets's calculate LCM of 492,886
2 | 492, 886 |
246, 443 |
∴ So the LCM of the given numbers is 2 x 246 x 443 = 217956
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 28/217956
Therefore, the GCF of Fractions 28/492,392/886 is 28/217956
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 492,886 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(492,886) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(492,886) x common factors =2 x 1 = 2
LCM(492,886) = ( 492 × 886 ) / 2
LCM(492,886) = 435912 / 2
LCM(492,886) = 217956
