I'm thinking of a number.
12 is a factor of my number.
What other factors MUST my number
have?
How many factors of
1 x 2 x 3 x 4 x 5 x 6
can you name without working out what
number it is?
1 x 2 x 3 x 4 x 5 x 6
Would you predict that 9 would be a
factor of this number?
1 x 2 x 3 x 4 x 5 x 6 =
1 x 2 x 3 x 2 x 2 x 5 x 2 x 3
How does this help us see that 9 is a
factor?
What factors do
2 x 3 x 4 x 5 x 6and
5 x 7 x 9
have in common?
What factors do
3 x 7 x 8 x 9 and
2 x 3 x 6 x 9
have in common?
What factors do
5 x 9 x 10 and200
have in common?
