Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 420/41,747/437
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 420,747
Greatest Common Factor of Numerators i.e. GCF of 420,747 is 3 .
LCM of Denominators means LCM of 41,437 as per the given fractions.
LCM of 41,437 is 17917 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 420,747
3 | 420, 747 |
140, 249 |
∴ So the GCF of the given numbers is 3 = 3

1,2,3,4,5,6,7,10,12,14,15,20,21,28,30,35,42,60,70,84,105,140,210,420
Factors of 747
List of positive integer factors of 747 that divides 747 without a remainder.
1,3,9,83,249,747
Greatest Common Factor
We found the factors 420,747 . The biggest common factor number is the GCF number.
So the greatest common factor 420,747 is 3.
Lets's calculate LCM of 41,437
Given numbers has no common factors except 1. So, there LCM is their product i.e 17917
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/17917
Therefore, the GCF of Fractions 420/41,747/437 is 3/17917
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 41,437 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(41,437) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(41,437) x common factors =1 x 1 = 1
LCM(41,437) = ( 41 × 437 ) / 1
LCM(41,437) = 17917 / 1
LCM(41,437) = 17917
