:1,2,4,5,8,10,16,20,32,40,64,80,128,160,256,320,640,1280
Greatest Common Factor
We found the factors 1480,1280 . The biggest common factor number is the GCF number.
So the greatest common factor 1480,1280 is 40.
Lets's calculate LCM of 489,946
Given numbers has no common factors except 1. So, there LCM is their product i.e 462594
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 40/462594
Therefore, the GCF of Fractions 1480/489,1280/946 is 40/462594
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 489,946 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(489,946) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(489,946) x common factors =1 x 1 = 1
LCM(489,946) = ( 489 × 946 ) / 1
LCM(489,946) = 462594 / 1
LCM(489,946) = 462594
