:1,2,4,8,16,32,64,128,256,512,1024
Greatest Common Factor
We found the factors 800,1024 . The biggest common factor number is the GCF number.
So the greatest common factor 800,1024 is 32.
Lets's calculate LCM of 146,457
Given numbers has no common factors except 1. So, there LCM is their product i.e 66722
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 32/66722
Therefore, the GCF of Fractions 800/146,1024/457 is 32/66722
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 146,457 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(146,457) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(146,457) x common factors =1 x 1 = 1
LCM(146,457) = ( 146 × 457 ) / 1
LCM(146,457) = 66722 / 1
LCM(146,457) = 66722
