Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 105/28,221/1647
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 105,221
Greatest Common Factor of Numerators i.e. GCF of 105,221 is 1 .
LCM of Denominators means LCM of 28,1647 as per the given fractions.
LCM of 28,1647 is 46116 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 105,221
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 105
List of positive integer factors of 105 that divides 105 without a remainder.
1,3,5,7,15,21,35,105
Factors of 221
List of positive integer factors of 221 that divides 221 without a remainder.
1,13,17,221
Greatest Common Factor
We found the factors 105,221 . The biggest common factor number is the GCF number.
So the greatest common factor 105,221 is 1.
Lets's calculate LCM of 28,1647
Given numbers has no common factors except 1. So, there LCM is their product i.e 46116
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/46116
Therefore, the GCF of Fractions 105/28,221/1647 is 1/46116
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 28,1647 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(28,1647) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(28,1647) x common factors =1 x 1 = 1
LCM(28,1647) = ( 28 × 1647 ) / 1
LCM(28,1647) = 46116 / 1
LCM(28,1647) = 46116
