Question

Check whether the given numbers are divisible by $4$ or not ?
(a) $3024$ (b) $1000$ (c) $412$ (d) $56240$

Answer 1

If the last two digits of a whole number are divisible by $4$, then the entire number is divisible by $4$
Above Rule can be applied as
$\left(a\right)3024\Rightarrow$ Last Digits are $24$ and $24$ is divisible by $4(24=6\times 4)$
therefore, the Number is divisible by $4$.
$\left(b\right)1000\Rightarrow$ Last Digits are $00$ or $0$ and $0$ is divisible by $4$ as $0$ is divisible by every integer or $(0=4\times 0)$.
therefore, the Number is divisible by $4$.
$\left(c\right)412\Rightarrow$ Last Digits are $12$ and $12$ is divisible by $4(12=4\times 3)$
therefore, the Number is divisible by $4$.
$\left(d\right)56240\Rightarrow$ Last Digits are $40$ and $40$ is divisible by $4(40=4\times 10)$
therefore, the Number is divisible by $4$.
