Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 458/21,888/355
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 458,888
Greatest Common Factor of Numerators i.e. GCF of 458,888 is 2 .
LCM of Denominators means LCM of 21,355 as per the given fractions.
LCM of 21,355 is 7455 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 458,888
2 | 458, 888 |
229, 444 |
∴ So the GCF of the given numbers is 2 = 2

1,2,229,458
Factors of 888
List of positive integer factors of 888 that divides 888 without a remainder.
1,2,3,4,6,8,12,24,37,74,111,148,222,296,444,888
Greatest Common Factor
We found the factors 458,888 . The biggest common factor number is the GCF number.
So the greatest common factor 458,888 is 2.
Lets's calculate LCM of 21,355
Given numbers has no common factors except 1. So, there LCM is their product i.e 7455
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/7455
Therefore, the GCF of Fractions 458/21,888/355 is 2/7455
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 21,355 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(21,355) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(21,355) x common factors =1 x 1 = 1
LCM(21,355) = ( 21 × 355 ) / 1
LCM(21,355) = 7455 / 1
LCM(21,355) = 7455
