Divisor Patterns
can be divided exactly by { .
6 6 3. 2. 1}
21 ;;i.{21. 7. 3. 1}
1 3 {1 3. 1 }
In this game we.shall forget about the divisor which is the same as the number we started
with.
1 2 {.M'. 6. 4. 3. 2. 1}
10 {.0. 5. 2. 1}
The sum of the divisors of 10 is : 5+2+1 = 8
Complete these patterns:
5 r 3 + 1 3 + 1 2+1
a
7+3+1
b
c
d
2 Will the patterns always end in the same way?
3 Investigate by starting with these numbers :
