:1,2,4,5,8,10,20,40,41,82,164,205,328,410,820,1640
Greatest Common Factor
We found the factors 90,1640 . The biggest common factor number is the GCF number.
So the greatest common factor 90,1640 is 10.
Lets's calculate LCM of 232,3405
Given numbers has no common factors except 1. So, there LCM is their product i.e 789960
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 10/789960
Therefore, the GCF of Fractions 90/232,1640/3405 is 10/789960
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 232,3405 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(232,3405) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(232,3405) x common factors =1 x 1 = 1
LCM(232,3405) = ( 232 × 3405 ) / 1
LCM(232,3405) = 789960 / 1
LCM(232,3405) = 789960
