Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 25/798,70/4843
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 25,70
Greatest Common Factor of Numerators i.e. GCF of 25,70 is 5 .
LCM of Denominators means LCM of 798,4843 as per the given fractions.
LCM of 798,4843 is 3864714 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 25,70
5 | 25, 70 |
5, 14 |
∴ So the GCF of the given numbers is 5 = 5
Factors of 25
List of positive integer factors of 25 that divides 25 without a remainder.
1,5,25
Factors of 70
List of positive integer factors of 70 that divides 70 without a remainder.
1,2,5,7,10,14,35,70
Greatest Common Factor
We found the factors 25,70 . The biggest common factor number is the GCF number.
So the greatest common factor 25,70 is 5.
Lets's calculate LCM of 798,4843
Given numbers has no common factors except 1. So, there LCM is their product i.e 3864714
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/3864714
Therefore, the GCF of Fractions 25/798,70/4843 is 5/3864714
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 798,4843 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(798,4843) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(798,4843) x common factors =1 x 1 = 1
LCM(798,4843) = ( 798 × 4843 ) / 1
LCM(798,4843) = 3864714 / 1
LCM(798,4843) = 3864714
