3 In this question, \(N\) is the number 26132652.
- Without dividing \(N\) by 13, explain why 13 is a factor of \(N\).
- Use standard divisibility tests to show that 36 is a factor of \(N\).
It is given that \(N = 36 \times 725907\).
- Use the results of parts (a) and (b) to deduce that 13 is a factor of 725907.
