Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 80/77,80/63,15/73,50/823
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 80,80,15,50
Greatest Common Factor of Numerators i.e. GCF of 80,80,15,50 is 5 .
LCM of Denominators means LCM of 77,63,73,823 as per the given fractions.
LCM of 77,63,73,823 is 41634747 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 80,80,15,50
5 | 80, 80, 15, 50 |
16, 16, 3, 10 |
∴ So the GCF of the given numbers is 5 = 5

Greatest Common Factor
We found the factors 80,80,15,50 . The biggest common factor number is the GCF number.
So the greatest common factor 80,80,15,50 is 5.
Lets's calculate LCM of 77,63,73,823
7 | 77, 63, 73, 823 |
11, 9, 73, 823 |
∴ So the LCM of the given numbers is 7 x 11 x 9 x 73 x 823 = 41634747
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/41634747
Therefore, the GCF of Fractions 80/77,80/63,15/73,50/823 is 5/41634747
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 77,63,73,823 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(77,63,73,823) = 1
common factors(in case of two or more numbers have common factors) = 7
GCF(77,63,73,823) x common factors =1 x 7 = 7
LCM(77,63,73,823) = ( 77 × 63 × 73 × 823 ) / 7
LCM(77,63,73,823) = 291443229 / 7
LCM(77,63,73,823) = 41634747
