1 is the answer.

Answer 2

If a number is divisible by 2, then 1 cannot be the one's digit in it.

• Each number has certain digits and its divisibility by another number depends on the position of those digits in the number.
• When dividing a number by 2, the number's one's or unit's digit should be 0, 4, 2, 6, or 8.
• If any other digit is at the unit's place, the given number will not be divisible by 2.
• So, 2 cannot divide a number like 361 without leaving a remainder.
