Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 29/36,31/37,40/72,35/54
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 29,31,40,35
Greatest Common Factor of Numerators i.e. GCF of 29,31,40,35 is 1 .
LCM of Denominators means LCM of 36,37,72,54 as per the given fractions.
LCM of 36,37,72,54 is 7992 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 29,31,40,35
∴ So GCF of numbers is 1 because of no common factors present between them.

Greatest Common Factor
We found the factors 29,31,40,35 . The biggest common factor number is the GCF number.
So the greatest common factor 29,31,40,35 is 1.
Lets's calculate LCM of 36,37,72,54
2 | 36, 37, 72, 54 |
2 | 18, 37, 36, 27 |
3 | 9, 37, 18, 27 |
3 | 3, 37, 6, 9 |
1, 37, 2, 3 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 3 x 1 x 37 x 2 x 3 = 7992
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/7992
Therefore, the GCF of Fractions 29/36,31/37,40/72,35/54 is 1/7992
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 36,37,72,54 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(36,37,72,54) = 1
common factors(in case of two or more numbers have common factors) = 648
GCF(36,37,72,54) x common factors =1 x 648 = 648
LCM(36,37,72,54) = ( 36 × 37 × 72 × 54 ) / 648
LCM(36,37,72,54) = 5178816 / 648
LCM(36,37,72,54) = 7992
