Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 783/13,411/211
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 783,411
Greatest Common Factor of Numerators i.e. GCF of 783,411 is 3 .
LCM of Denominators means LCM of 13,211 as per the given fractions.
LCM of 13,211 is 2743 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 783,411
3 | 783, 411 |
261, 137 |
∴ So the GCF of the given numbers is 3 = 3

1,3,9,27,29,87,261,783
Factors of 411
List of positive integer factors of 411 that divides 411 without a remainder.
1,3,137,411
Greatest Common Factor
We found the factors 783,411 . The biggest common factor number is the GCF number.
So the greatest common factor 783,411 is 3.
Lets's calculate LCM of 13,211
Given numbers has no common factors except 1. So, there LCM is their product i.e 2743
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/2743
Therefore, the GCF of Fractions 783/13,411/211 is 3/2743
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 13,211 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(13,211) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(13,211) x common factors =1 x 1 = 1
LCM(13,211) = ( 13 × 211 ) / 1
LCM(13,211) = 2743 / 1
LCM(13,211) = 2743
