Determine GCF(25,30)
GCF = Largest factor that divides numbers
1,5,25
1,2,3,5,6,10,15
1,5
GCF(25,30) = 5
Since GCF ≠ 1, they are not relatively prime (co-prime)
Since GCF ≠ 1 and have a difference of two, the numbers are not twin prime
Calculate LCM for the following
(25,30)
25,50,75,100,125,150,175,200,225
30,60,90,120,150,180,210,240
