Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 40/11,14/72,570/39
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 40,14,570
Greatest Common Factor of Numerators i.e. GCF of 40,14,570 is 2 .
LCM of Denominators means LCM of 11,72,39 as per the given fractions.
LCM of 11,72,39 is 10296 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 40,14,570
2 | 40, 14, 570 |
20, 7, 285 |
∴ So the GCF of the given numbers is 2 = 2

1,2,3,5,6,10,15,19,30,38,57,95,114,190,285,570
Greatest Common Factor
We found the factors 40,14,570 . The biggest common factor number is the GCF number.
So the greatest common factor 40,14,570 is 2.
Lets's calculate LCM of 11,72,39
3 | 11, 72, 39 |
11, 24, 13 |
∴ So the LCM of the given numbers is 3 x 11 x 24 x 13 = 10296
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/10296
Therefore, the GCF of Fractions 40/11,14/72,570/39 is 2/10296
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 11,72,39 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(11,72,39) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(11,72,39) x common factors =1 x 3 = 3
LCM(11,72,39) = ( 11 × 72 × 39 ) / 3
LCM(11,72,39) = 30888 / 3
LCM(11,72,39) = 10296
