The possibilities for a digit in the ones place of a prime number greater than 5 are 1, 3, 7, and 9. If a 0, 2, 4, 6, or 8 is in the ones place, the number is divisible by 2, so it would not be prime. If a 5 is in the ones place, the number is divisible by 5, so it would not be prime.
No, all numbers with a zero in the one's place are divisible by at least 1, themselves, and 2, which means they cannot be prime.
185 is composite because anything that has 5 in the ones place is always divisible by 5. A prime number is a number that can only divided equally by itself and 1, so since 185 is divisible by 185, 1, 5, and 37, it is not a prime number.
Only one positive prime number has a 5 in the ones digit. That prime number is 5. All other numbers with a 5 in the ones digit are composite because they will be divisible by 5.
The digit 2 is in the ones place
2, 3, 5, and 7 are prime numbers for one digit numbers. 1 is NOT a prime number.
Larger. See which number is larger 1,000 [Thousands place] or 1 [Ones place]
no 1 is not a prime number
A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite. A number cannot be both.
A prime number is a number which only 1 and itself go into. In this case the obvious ones are 1, 2 and 336. Which mean it is not a prime number because of the 2. (There will be more than them 3 numbers, I just dont want to list them all)
