Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 109/677,3989/820
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 109,3989
Greatest Common Factor of Numerators i.e. GCF of 109,3989 is 1 .
LCM of Denominators means LCM of 677,820 as per the given fractions.
LCM of 677,820 is 555140 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 109,3989
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 109
List of positive integer factors of 109 that divides 109 without a remainder.
1,109
Factors of 3989
List of positive integer factors of 3989 that divides 3989 without a remainder.
1,3989
Greatest Common Factor
We found the factors 109,3989 . The biggest common factor number is the GCF number.
So the greatest common factor 109,3989 is 1.
Lets's calculate LCM of 677,820
Given numbers has no common factors except 1. So, there LCM is their product i.e 555140
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/555140
Therefore, the GCF of Fractions 109/677,3989/820 is 1/555140
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 677,820 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(677,820) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(677,820) x common factors =1 x 1 = 1
LCM(677,820) = ( 677 × 820 ) / 1
LCM(677,820) = 555140 / 1
LCM(677,820) = 555140
