Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 50/77,55/72,200/31
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 50,55,200
Greatest Common Factor of Numerators i.e. GCF of 50,55,200 is 5 .
LCM of Denominators means LCM of 77,72,31 as per the given fractions.
LCM of 77,72,31 is 171864 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 50,55,200
5 | 50, 55, 200 |
10, 11, 40 |
∴ So the GCF of the given numbers is 5 = 5
Factors of 50
List of positive integer factors of 50 that divides 50 without a remainder.
1,2,5,10,25,50
Factors of 55
List of positive integer factors of 55 that divides 55 without a remainder.
1,5,11,55
Factors of 200
List of positive integer factors of 200 that divides 200 without a remainder.
1,2,4,5,8,10,20,25,40,50,100,200
Greatest Common Factor
We found the factors 50,55,200 . The biggest common factor number is the GCF number.
So the greatest common factor 50,55,200 is 5.
Lets's calculate LCM of 77,72,31
Given numbers has no common factors except 1. So, there LCM is their product i.e 171864
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/171864
Therefore, the GCF of Fractions 50/77,55/72,200/31 is 5/171864
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 77,72,31 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(77,72,31) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(77,72,31) x common factors =1 x 1 = 1
LCM(77,72,31) = ( 77 × 72 × 31 ) / 1
LCM(77,72,31) = 171864 / 1
LCM(77,72,31) = 171864
Here are some samples of GCF of Fractions calculations.
