Notes
M1: for continual prime factorisation (at least two correct steps anywhere) or at least two stages of a factor tree, or table, correct.
eg if first stage wrong, 800 × 80 then 800 = 80 × 10 and 80 = 40 × 2 would count as 2 correct steps.
M1: dep M1 for a fully correct factor tree or a list (2,2,2,2,5,11) condone inclusion of 1’s on branch ends.
or 2 × 2 × 2 × 2 × 5 × 11
A1: dep M2 for \(2^4 \times 5 \times 11\) (with working seen)
