How can you tell 28655 not a prime number looking at the last digit?

Answer 1

All numbers ending in 0 and 5 are divisible by 5 and since 28655 ends in 5, it is divisible by 5 and therefore not prime.

Answer 2

Well, friend, when we look at the last digit of a number, if it ends in 5, like 28655 does, then it's not a Prime number. You see, prime numbers can only end in 1, 3, 7, or 9. So, we can tell just by looking at the last digit that 28655 is not a prime number.

Answer 3

Oh, dude, like if the last digit of a number is 5, you can tell it's not a prime number because all prime numbers end in 1, 3, 7, or 9. So, like, 28655 ends in 5, which means it's not a prime number. Easy peasy, right?

Answer 4

To determine if a number is divisible by 5, you only need to look at its last digit. If the last digit is 0 or 5, then the number is divisible by 5. In the case of 28655, the last digit is 5, which means it is divisible by 5. Therefore, 28655 is not a prime number.
