Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 221/81,851/238
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 221,851
Greatest Common Factor of Numerators i.e. GCF of 221,851 is 1 .
LCM of Denominators means LCM of 81,238 as per the given fractions.
LCM of 81,238 is 19278 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 221,851
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 221
List of positive integer factors of 221 that divides 221 without a remainder.
1,13,17,221
Factors of 851
List of positive integer factors of 851 that divides 851 without a remainder.
1,23,37,851
Greatest Common Factor
We found the factors 221,851 . The biggest common factor number is the GCF number.
So the greatest common factor 221,851 is 1.
Lets's calculate LCM of 81,238
Given numbers has no common factors except 1. So, there LCM is their product i.e 19278
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/19278
Therefore, the GCF of Fractions 221/81,851/238 is 1/19278
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 81,238 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(81,238) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(81,238) x common factors =1 x 1 = 1
LCM(81,238) = ( 81 × 238 ) / 1
LCM(81,238) = 19278 / 1
LCM(81,238) = 19278
