Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 32/207,921/855
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 32,921
Greatest Common Factor of Numerators i.e. GCF of 32,921 is 1 .
LCM of Denominators means LCM of 207,855 as per the given fractions.
LCM of 207,855 is 19665 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 32,921
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 32
List of positive integer factors of 32 that divides 32 without a remainder.
1,2,4,8,16,32
Factors of 921
List of positive integer factors of 921 that divides 921 without a remainder.
1,3,307,921
Greatest Common Factor
We found the factors 32,921 . The biggest common factor number is the GCF number.
So the greatest common factor 32,921 is 1.
Lets's calculate LCM of 207,855
3 | 207, 855 |
3 | 69, 285 |
23, 95 |
∴ So the LCM of the given numbers is 3 x 3 x 23 x 95 = 19665
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/19665
Therefore, the GCF of Fractions 32/207,921/855 is 1/19665
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 207,855 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(207,855) = 9
common factors(in case of two or more numbers have common factors) = 1
GCF(207,855) x common factors =9 x 1 = 9
LCM(207,855) = ( 207 × 855 ) / 9
LCM(207,855) = 176985 / 9
LCM(207,855) = 19665
