:1,3,9,211,633,1899
Now, list down the factors of 1980
:1,2,3,4,5,6,9,10,11,12,15,18,20,22,30,33,36,44,45,55,60,66,90,99,110,132,165,180,198,220,330,396,495,660,990,1980
Greatest Common Factor
We found the factors 1899,1980 . The biggest common factor number is the GCF number.
So the greatest common factor 1899,1980 is 9.
Lets's calculate LCM of 649,565
Given numbers has no common factors except 1. So, there LCM is their product i.e 366685
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/366685
Therefore, the GCF of Fractions 1899/649,1980/565 is 9/366685
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 649,565 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(649,565) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(649,565) x common factors =1 x 1 = 1
LCM(649,565) = ( 649 × 565 ) / 1
LCM(649,565) = 366685 / 1
LCM(649,565) = 366685
