Write down all the factors that they have in common and then choose the biggest one.

2. across

1. Break the numbers down into their prime-power factorization:$6=2^1\cdot3^1$$8=2^3\cdot3^0$2. Take the minimum of each:$2^1\cdot3^0=2$

thats the fancy way here's how I do it: first I ask myself "what times what equals 6?" 6 times 1 and 2 times 3 "what times what equals 8" 8 times 1 and 2 times 4 "what's the biggest number that both of those have?" 2 =)
