Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 71/392,860/115
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 71,860
Greatest Common Factor of Numerators i.e. GCF of 71,860 is 1 .
LCM of Denominators means LCM of 392,115 as per the given fractions.
LCM of 392,115 is 45080 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 71,860
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 71
List of positive integer factors of 71 that divides 71 without a remainder.
1,71
Factors of 860
List of positive integer factors of 860 that divides 860 without a remainder.
1,2,4,5,10,20,43,86,172,215,430,860
Greatest Common Factor
We found the factors 71,860 . The biggest common factor number is the GCF number.
So the greatest common factor 71,860 is 1.
Lets's calculate LCM of 392,115
Given numbers has no common factors except 1. So, there LCM is their product i.e 45080
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/45080
Therefore, the GCF of Fractions 71/392,860/115 is 1/45080
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 392,115 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(392,115) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(392,115) x common factors =1 x 1 = 1
LCM(392,115) = ( 392 × 115 ) / 1
LCM(392,115) = 45080 / 1
LCM(392,115) = 45080
