Question 2 (d)

Using divisibility test, determine whether the given number is divisible by 4; by 8:
6000

Answer 1

Divisibility rule for 4: A number with 3 or more digits is divisible by 4 if the number formed by its last two digits (i.e. ones and tens) is divisible by 4.
Divisibility rule for 8: A number with 4 or more digits is divisible by 8 if the number formed by the last three digits is divisible by 8.

Applying the above divisibility rules,
6000 $\to$ Divisible by 4 as its last two digits are 0.
6000 $\to$ Divisible by 8 as its last three digits are 0.
