Question

789101112131415x leaves no reminder when divided by 8 what is the value of x

Answer 1

for divisibility by 8 last 3 digits should be divisible by 8

so 15X should be divisible by 8

So it's 9 as 152 is divisible by 8

Answer 2

Answer: 2

Step-by-step explanation:

A number having more than 3 digits is divisible by 8,

If the last three digit of the number is divisible by 8,

Here x represents the last digit of the given number,

We will check by substituting x = 0, 2, 4, 6, 8 ( Because it must be even number)

If x = 2,

⇒ 152 is divisible by 8,

⇒ The value of x can be 8.

But for x = 0, 4, 6 and 8,

⇒ 150, 154, 156 and 158 are not divisible by 8,

⇒ The value of x can not be equal to 0, 4, 6 or 8.

Thus, the required value of x for which 789101112131415x is divisible by 8 is 2.
