Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 689/817,1059/827
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 689,1059
Greatest Common Factor of Numerators i.e. GCF of 689,1059 is 1 .
LCM of Denominators means LCM of 817,827 as per the given fractions.
LCM of 817,827 is 675659 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 689,1059
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 689
List of positive integer factors of 689 that divides 689 without a remainder.
1,13,53,689
Factors of 1059
List of positive integer factors of 1059 that divides 1059 without a remainder.
1,3,353,1059
Greatest Common Factor
We found the factors 689,1059 . The biggest common factor number is the GCF number.
So the greatest common factor 689,1059 is 1.
Lets's calculate LCM of 817,827
Given numbers has no common factors except 1. So, there LCM is their product i.e 675659
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/675659
Therefore, the GCF of Fractions 689/817,1059/827 is 1/675659
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 817,827 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(817,827) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(817,827) x common factors =1 x 1 = 1
LCM(817,827) = ( 817 × 827 ) / 1
LCM(817,827) = 675659 / 1
LCM(817,827) = 675659
