Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 397/290,1945/487
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 397,1945
Greatest Common Factor of Numerators i.e. GCF of 397,1945 is 1 .
LCM of Denominators means LCM of 290,487 as per the given fractions.
LCM of 290,487 is 141230 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 397,1945
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 397
List of positive integer factors of 397 that divides 397 without a remainder.
1,397
Factors of 1945
List of positive integer factors of 1945 that divides 1945 without a remainder.
1,5,389,1945
Greatest Common Factor
We found the factors 397,1945 . The biggest common factor number is the GCF number.
So the greatest common factor 397,1945 is 1.
Lets's calculate LCM of 290,487
Given numbers has no common factors except 1. So, there LCM is their product i.e 141230
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/141230
Therefore, the GCF of Fractions 397/290,1945/487 is 1/141230
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 290,487 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(290,487) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(290,487) x common factors =1 x 1 = 1
LCM(290,487) = ( 290 × 487 ) / 1
LCM(290,487) = 141230 / 1
LCM(290,487) = 141230
