Answer:

numbers are: 23456

Step-by-step explanation:

This shows you the divisibility tests for 2, 3, 5, 7, and 11, so you can tell if those numbers are factors of a given number or not without dividing

Divisibility Test for 2: The last digit is 0, 2, 4, 6, or 8. in no. 23456 one's place digit is 6 so divisible.

Divisibility Test for 3: The sum of the digits is divisible by 3. add all no 2+3+4+5+6=20, 20 is not divisible by 3 so no is not divisible.

Divisible by 4 •The last 2 digits should be divisible by both 2 and 4.

Divisibility Test for 5: The last digit is 0 or 5.

last digit is not 0 or 5 so not divisible.

Divisibility Rule of Six

A number is divisible by 6, if it is divisible by both 2 and 3.

Divisibility Test for 7: Cross off last digit, double it and subtract. Repeat if you want. If new number is divisible by 7, the original number is divisible by 7.

Divisible by 8•The last 3 digits should be divisible by 8.

Divisibility Test for 9: The sum of the digits is divisible by 9.

Divisibility Test for 10: The last digit should be 0.

Divisibility Test for 11: For a 3-digit number, sum of the outside digits minus the middle digit must be 0 or 11.

this way you go for all test.
