Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 490/89,4207/809
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 490,4207
Greatest Common Factor of Numerators i.e. GCF of 490,4207 is 7 .
LCM of Denominators means LCM of 89,809 as per the given fractions.
LCM of 89,809 is 72001 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 490,4207
7 | 490, 4207 |
70, 601 |
∴ So the GCF of the given numbers is 7 = 7

Factors of 4207
List of positive integer factors of 4207 that divides 4207 without a remainder.
1,7,601,4207
Greatest Common Factor
We found the factors 490,4207 . The biggest common factor number is the GCF number.
So the greatest common factor 490,4207 is 7.
Lets's calculate LCM of 89,809
Given numbers has no common factors except 1. So, there LCM is their product i.e 72001
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/72001
Therefore, the GCF of Fractions 490/89,4207/809 is 7/72001
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 89,809 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(89,809) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(89,809) x common factors =1 x 1 = 1
LCM(89,809) = ( 89 × 809 ) / 1
LCM(89,809) = 72001 / 1
LCM(89,809) = 72001
