Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 389/52,391/54,172/67
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 389,391,172
Greatest Common Factor of Numerators i.e. GCF of 389,391,172 is 1 .
LCM of Denominators means LCM of 52,54,67 as per the given fractions.
LCM of 52,54,67 is 94068 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 389,391,172
∴ So GCF of numbers is 1 because of no common factors present between them.

1,2,4,43,86,172
Greatest Common Factor
We found the factors 389,391,172 . The biggest common factor number is the GCF number.
So the greatest common factor 389,391,172 is 1.
Lets's calculate LCM of 52,54,67
2 | 52, 54, 67 |
26, 27, 67 |
∴ So the LCM of the given numbers is 2 x 26 x 27 x 67 = 94068
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/94068
Therefore, the GCF of Fractions 389/52,391/54,172/67 is 1/94068
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 52,54,67 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(52,54,67) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(52,54,67) x common factors =1 x 2 = 2
LCM(52,54,67) = ( 52 × 54 × 67 ) / 2
LCM(52,54,67) = 188136 / 2
LCM(52,54,67) = 94068
