Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 41/35,32/78,642/21
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 41,32,642
Greatest Common Factor of Numerators i.e. GCF of 41,32,642 is 1 .
LCM of Denominators means LCM of 35,78,21 as per the given fractions.
LCM of 35,78,21 is 2730 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 41,32,642
∴ So GCF of numbers is 1 because of no common factors present between them.

1,2,3,6,107,214,321,642
Greatest Common Factor
We found the factors 41,32,642 . The biggest common factor number is the GCF number.
So the greatest common factor 41,32,642 is 1.
Lets's calculate LCM of 35,78,21
3 | 35, 78, 21 |
7 | 35, 26, 7 |
5, 26, 1 |
∴ So the LCM of the given numbers is 3 x 7 x 5 x 26 x 1 = 2730
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2730
Therefore, the GCF of Fractions 41/35,32/78,642/21 is 1/2730
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 35,78,21 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(35,78,21) = 1
common factors(in case of two or more numbers have common factors) = 21
GCF(35,78,21) x common factors =1 x 21 = 21
LCM(35,78,21) = ( 35 × 78 × 21 ) / 21
LCM(35,78,21) = 57330 / 21
LCM(35,78,21) = 2730
