Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 391/27,128/646
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 391,128
Greatest Common Factor of Numerators i.e. GCF of 391,128 is 1 .
LCM of Denominators means LCM of 27,646 as per the given fractions.
LCM of 27,646 is 17442 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 391,128
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 391
List of positive integer factors of 391 that divides 391 without a remainder.
1,17,23,391
Factors of 128
List of positive integer factors of 128 that divides 128 without a remainder.
1,2,4,8,16,32,64,128
Greatest Common Factor
We found the factors 391,128 . The biggest common factor number is the GCF number.
So the greatest common factor 391,128 is 1.
Lets's calculate LCM of 27,646
Given numbers has no common factors except 1. So, there LCM is their product i.e 17442
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/17442
Therefore, the GCF of Fractions 391/27,128/646 is 1/17442
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 27,646 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(27,646) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(27,646) x common factors =1 x 1 = 1
LCM(27,646) = ( 27 × 646 ) / 1
LCM(27,646) = 17442 / 1
LCM(27,646) = 17442
