Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 488/821,900/428
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 488,900
Greatest Common Factor of Numerators i.e. GCF of 488,900 is 4 .
LCM of Denominators means LCM of 821,428 as per the given fractions.
LCM of 821,428 is 351388 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 488,900
2 | 488, 900 |
2 | 244, 450 |
122, 225 |
∴ So the GCF of the given numbers is 2 x 2 = 4

Greatest Common Factor
We found the factors 488,900 . The biggest common factor number is the GCF number.
So the greatest common factor 488,900 is 4.
Lets's calculate LCM of 821,428
Given numbers has no common factors except 1. So, there LCM is their product i.e 351388
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/351388
Therefore, the GCF of Fractions 488/821,900/428 is 4/351388
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 821,428 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(821,428) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(821,428) x common factors =1 x 1 = 1
LCM(821,428) = ( 821 × 428 ) / 1
LCM(821,428) = 351388 / 1
LCM(821,428) = 351388
