Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 71/41,21/40,573/220
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 71,21,573
Greatest Common Factor of Numerators i.e. GCF of 71,21,573 is 1 .
LCM of Denominators means LCM of 41,40,220 as per the given fractions.
LCM of 41,40,220 is 18040 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 71,21,573
∴ So GCF of numbers is 1 because of no common factors present between them.

1,3,7,21
Factors of 573
List of positive integer factors of 573 that divides 573 without a remainder.
1,3,191,573
Greatest Common Factor
We found the factors 71,21,573 . The biggest common factor number is the GCF number.
So the greatest common factor 71,21,573 is 1.
Lets's calculate LCM of 41,40,220
2 | 41, 40, 220 |
2 | 41, 20, 110 |
5 | 41, 10, 55 |
41, 2, 11 |
∴ So the LCM of the given numbers is 2 x 2 x 5 x 41 x 2 x 11 = 18040
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/18040
Therefore, the GCF of Fractions 71/41,21/40,573/220 is 1/18040
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 41,40,220 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(41,40,220) = 1
common factors(in case of two or more numbers have common factors) = 20
GCF(41,40,220) x common factors =1 x 20 = 20
LCM(41,40,220) = ( 41 × 40 × 220 ) / 20
LCM(41,40,220) = 360800 / 20
LCM(41,40,220) = 18040
