Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 221/90,4724/860
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 221,4724
Greatest Common Factor of Numerators i.e. GCF of 221,4724 is 1 .
LCM of Denominators means LCM of 90,860 as per the given fractions.
LCM of 90,860 is 7740 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 221,4724
∴ 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 4724
List of positive integer factors of 4724 that divides 4724 without a remainder.
1,2,4,1181,2362,4724
Greatest Common Factor
We found the factors 221,4724 . The biggest common factor number is the GCF number.
So the greatest common factor 221,4724 is 1.
Lets's calculate LCM of 90,860
2 | 90, 860 |
5 | 45, 430 |
9, 86 |
∴ So the LCM of the given numbers is 2 x 5 x 9 x 86 = 7740
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/7740
Therefore, the GCF of Fractions 221/90,4724/860 is 1/7740
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 90,860 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(90,860) = 10
common factors(in case of two or more numbers have common factors) = 1
GCF(90,860) x common factors =10 x 1 = 10
LCM(90,860) = ( 90 × 860 ) / 10
LCM(90,860) = 77400 / 10
LCM(90,860) = 7740
