:1,2,4,197,394,788
Now, list down the factors of 620
:1,2,4,5,10,20,31,62,124,155,310,620
Greatest Common Factor
We found the factors 788,620 . The biggest common factor number is the GCF number.
So the greatest common factor 788,620 is 4.
Lets's calculate LCM of 443,391
Given numbers has no common factors except 1. So, there LCM is their product i.e 173213
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/173213
Therefore, the GCF of Fractions 788/443,620/391 is 4/173213
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 443,391 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(443,391) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(443,391) x common factors =1 x 1 = 1
LCM(443,391) = ( 443 × 391 ) / 1
LCM(443,391) = 173213 / 1
LCM(443,391) = 173213
