Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 808/91,790/473
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 808,790
Greatest Common Factor of Numerators i.e. GCF of 808,790 is 2 .
LCM of Denominators means LCM of 91,473 as per the given fractions.
LCM of 91,473 is 43043 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 808,790
2 | 808, 790 |
404, 395 |
∴ So the GCF of the given numbers is 2 = 2

1,2,4,8,101,202,404,808
Factors of 790
List of positive integer factors of 790 that divides 790 without a remainder.
1,2,5,10,79,158,395,790
Greatest Common Factor
We found the factors 808,790 . The biggest common factor number is the GCF number.
So the greatest common factor 808,790 is 2.
Lets's calculate LCM of 91,473
Given numbers has no common factors except 1. So, there LCM is their product i.e 43043
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/43043
Therefore, the GCF of Fractions 808/91,790/473 is 2/43043
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 91,473 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(91,473) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(91,473) x common factors =1 x 1 = 1
LCM(91,473) = ( 91 × 473 ) / 1
LCM(91,473) = 43043 / 1
LCM(91,473) = 43043
