Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 27/398,554/711
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 27,554
Greatest Common Factor of Numerators i.e. GCF of 27,554 is 1 .
LCM of Denominators means LCM of 398,711 as per the given fractions.
LCM of 398,711 is 282978 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 27,554
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 27
List of positive integer factors of 27 that divides 27 without a remainder.
1,3,9,27
Factors of 554
List of positive integer factors of 554 that divides 554 without a remainder.
1,2,277,554
Greatest Common Factor
We found the factors 27,554 . The biggest common factor number is the GCF number.
So the greatest common factor 27,554 is 1.
Lets's calculate LCM of 398,711
Given numbers has no common factors except 1. So, there LCM is their product i.e 282978
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/282978
Therefore, the GCF of Fractions 27/398,554/711 is 1/282978
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 398,711 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(398,711) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(398,711) x common factors =1 x 1 = 1
LCM(398,711) = ( 398 × 711 ) / 1
LCM(398,711) = 282978 / 1
LCM(398,711) = 282978
