Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 206/67,408/7765
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 206,408
Greatest Common Factor of Numerators i.e. GCF of 206,408 is 2 .
LCM of Denominators means LCM of 67,7765 as per the given fractions.
LCM of 67,7765 is 520255 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 206,408
2 | 206, 408 |
103, 204 |
∴ So the GCF of the given numbers is 2 = 2

1,2,103,206
Factors of 408
List of positive integer factors of 408 that divides 408 without a remainder.
1,2,3,4,6,8,12,17,24,34,51,68,102,136,204,408
Greatest Common Factor
We found the factors 206,408 . The biggest common factor number is the GCF number.
So the greatest common factor 206,408 is 2.
Lets's calculate LCM of 67,7765
Given numbers has no common factors except 1. So, there LCM is their product i.e 520255
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/520255
Therefore, the GCF of Fractions 206/67,408/7765 is 2/520255
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 67,7765 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(67,7765) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(67,7765) x common factors =1 x 1 = 1
LCM(67,7765) = ( 67 × 7765 ) / 1
LCM(67,7765) = 520255 / 1
LCM(67,7765) = 520255
