Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 921/547,387/943
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 921,387
Greatest Common Factor of Numerators i.e. GCF of 921,387 is 3 .
LCM of Denominators means LCM of 547,943 as per the given fractions.
LCM of 547,943 is 515821 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 921,387
3 | 921, 387 |
307, 129 |
∴ So the GCF of the given numbers is 3 = 3
Factors of 921
List of positive integer factors of 921 that divides 921 without a remainder.
1,3,307,921
Factors of 387
List of positive integer factors of 387 that divides 387 without a remainder.
1,3,9,43,129,387
Greatest Common Factor
We found the factors 921,387 . The biggest common factor number is the GCF number.
So the greatest common factor 921,387 is 3.
Lets's calculate LCM of 547,943
Given numbers has no common factors except 1. So, there LCM is their product i.e 515821
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/515821
Therefore, the GCF of Fractions 921/547,387/943 is 3/515821
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 547,943 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(547,943) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(547,943) x common factors =1 x 1 = 1
LCM(547,943) = ( 547 × 943 ) / 1
LCM(547,943) = 515821 / 1
LCM(547,943) = 515821
