### Divisibility Rules

1. 1. DIVISIBILITY RULES BY FIONA MARGE
2. 2. DEFINITIONS • Divisibility Rules: The method you follow to determine if a number is divisible by another. • Divisible: When you divide a number with another and get no remainder.
3. 3. 1 • All numbers are divisible by 1.
4. 4. 2 • The last digit of the number needs to be even. Example: 48: Last digit is even so it is divisible by 2.
5. 5. 3 • The sum of all digits should be a multiple of 3. Example: 243: 2+4+3=9 (3x3=9) so it is divisible by 3.
6. 6. 4 • The last two digits of the number need to be a multiple of 4. Example: 224: (4x6=24) so it is divisible by 4.
7. 7. 5 • The last digit needs to end with either a 5 or 0. Example: 225: Ends with 5, so it is divisible by 5.
8. 8. 6 • The number needs to be divisible by 2 and 3. Example: 222: Divisible by 2 2+2+2=6 Divisible by 3 So it is divisible by 6.
9. 9. 7 • You need to divide the number by 7. Example: 28 divided by 7=4 r0 It is divisible by 7.
10. 10. 8 • You need to divide the number by 8. Example: 24 divided by 8=3 It is divisible by 8.
11. 11. 9 • The sum of all the digits must be a multiple of 9. Example: 3213: 3+2+1+3=9 It is divisible by 9.
12. 12. 10 • The number must end with a 0. Example: 280: It is divisible by 10.
13. 13. THE END! I hope this PowerPoint helped you and it will be posted on Moodle. 
