Question

find the values for different that make the indicated divisibility test successful 98942d is divisible by 4

Answer 1

`0\text{ or 4 or 8}`

Note

Firstly, The basic rule for divisibility by 4 is that if the number formed by the last two digits in a number is divisible by 4, the original number is divisible by 4

Secondly, If the last two digits end with 00 this is because 100 is divisible by 4 and so adding hundreds, thousands, etc. 4 can divide perfectly.

Given

The divisibility test successful 98942d is divisible by 4​

`\begin{gathered} 20 \\ 24 \\ 28 \\ \text{all divisible by 4} \end{gathered}`

Therefore d can be

`0\text{ or 4 or 8}`

The final answer

d is either

0 or 4 or 8
