Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 285/429,1730/947
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 285,1730
Greatest Common Factor of Numerators i.e. GCF of 285,1730 is 5 .
LCM of Denominators means LCM of 429,947 as per the given fractions.
LCM of 429,947 is 406263 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 285,1730
5 | 285, 1730 |
57, 346 |
∴ So the GCF of the given numbers is 5 = 5

List of positive integer factors of 1730 that divides 1730 without a remainder.
1,2,5,10,173,346,865,1730
Greatest Common Factor
We found the factors 285,1730 . The biggest common factor number is the GCF number.
So the greatest common factor 285,1730 is 5.
Lets's calculate LCM of 429,947
Given numbers has no common factors except 1. So, there LCM is their product i.e 406263
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/406263
Therefore, the GCF of Fractions 285/429,1730/947 is 5/406263
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 429,947 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(429,947) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(429,947) x common factors =1 x 1 = 1
LCM(429,947) = ( 429 × 947 ) / 1
LCM(429,947) = 406263 / 1
LCM(429,947) = 406263
Here are some samples of GCF of Fractions calculations.
