Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 3/86,147/58,129/65
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 3,147,129
Greatest Common Factor of Numerators i.e. GCF of 3,147,129 is 3 .
LCM of Denominators means LCM of 86,58,65 as per the given fractions.
LCM of 86,58,65 is 162110 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 3,147,129
3 | 3, 147, 129 |
1, 49, 43 |
∴ So the GCF of the given numbers is 3 = 3

Factors of 129
List of positive integer factors of 129 that divides 129 without a remainder.
1,3,43,129
Greatest Common Factor
We found the factors 3,147,129 . The biggest common factor number is the GCF number.
So the greatest common factor 3,147,129 is 3.
Lets's calculate LCM of 86,58,65
2 | 86, 58, 65 |
43, 29, 65 |
∴ So the LCM of the given numbers is 2 x 43 x 29 x 65 = 162110
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/162110
Therefore, the GCF of Fractions 3/86,147/58,129/65 is 3/162110
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 86,58,65 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(86,58,65) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(86,58,65) x common factors =1 x 2 = 2
LCM(86,58,65) = ( 86 × 58 × 65 ) / 2
LCM(86,58,65) = 324220 / 2
LCM(86,58,65) = 162110
