Answer 2

$\huge\bold{\mathtt{Question⇒}}$

Determine if 263921 is divisible by 3.

$\huge\bold{\mathtt{To\:find⇒}}$

Whether the number is divisible by 3.

$\huge\bold{\mathtt{Solution⇒}}$

We know that:

A number is divisible by 3 only if the sum of its digits is divisible by 3.

Here, the number is 263921.

Sum of its digits⇒

2+6+3+9+2+1

= 23

23 is not divisible by 3.

Hence, the number 263921 is not divisible by 3.

$\huge\bold{\mathtt{Not\:sure\:??}}$

$\huge\bold{\mathtt{Verification⇒}}$

263921 ÷ 3

= 87973$\frac{2}{3}$

So, 263921 is not divisible by 3.

Hence, verified.
