Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 785/23,120/894
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 785,120
Greatest Common Factor of Numerators i.e. GCF of 785,120 is 5 .
LCM of Denominators means LCM of 23,894 as per the given fractions.
LCM of 23,894 is 20562 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 785,120
5 | 785, 120 |
157, 24 |
∴ So the GCF of the given numbers is 5 = 5
Factors of 785
List of positive integer factors of 785 that divides 785 without a remainder.
1,5,157,785
Factors of 120
List of positive integer factors of 120 that divides 120 without a remainder.
1,2,3,4,5,6,8,10,12,15,20,24,30,40,60,120
Greatest Common Factor
We found the factors 785,120 . The biggest common factor number is the GCF number.
So the greatest common factor 785,120 is 5.
Lets's calculate LCM of 23,894
Given numbers has no common factors except 1. So, there LCM is their product i.e 20562
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/20562
Therefore, the GCF of Fractions 785/23,120/894 is 5/20562
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 23,894 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(23,894) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(23,894) x common factors =1 x 1 = 1
LCM(23,894) = ( 23 × 894 ) / 1
LCM(23,894) = 20562 / 1
LCM(23,894) = 20562
Here are some samples of GCF of Fractions calculations.
