Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 788/21,421/9638
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 788,421
Greatest Common Factor of Numerators i.e. GCF of 788,421 is 1 .
LCM of Denominators means LCM of 21,9638 as per the given fractions.
LCM of 21,9638 is 202398 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 788,421
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 788
List of positive integer factors of 788 that divides 788 without a remainder.
1,2,4,197,394,788
Factors of 421
List of positive integer factors of 421 that divides 421 without a remainder.
1,421
Greatest Common Factor
We found the factors 788,421 . The biggest common factor number is the GCF number.
So the greatest common factor 788,421 is 1.
Lets's calculate LCM of 21,9638
Given numbers has no common factors except 1. So, there LCM is their product i.e 202398
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/202398
Therefore, the GCF of Fractions 788/21,421/9638 is 1/202398
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 21,9638 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(21,9638) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(21,9638) x common factors =1 x 1 = 1
LCM(21,9638) = ( 21 × 9638 ) / 1
LCM(21,9638) = 202398 / 1
LCM(21,9638) = 202398
