i) When number is divide by 2: if the last digit of the number is even number then is divide by 2.
ii) When number is divide by 4 - If the last two digits of the number is divide by 4, then the number is divisible by 4.
For example, we have 15237716 then 16 ÷ 4 = 4.
iii) When divide by 5 - If the number ends with the 5 or 0 then that number is divide by 5.
iv)When number is divide by 9 - if the sum of all the digits in the number is divisible by 9, then the number is divisible by 9.
For example, we have 183321477 is divisible by 9
