Question

how do i find the greatest common factor of 6,8

Answer 1

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

Answer 2

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:\[2^1\cdot3^0=2\]

Answer 3

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?"
