What are the only 4 possibilities for the ones-place digits of all primes greater than 5?
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.
Can a whole number with zero in the ones place 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.
Is 185 composite or 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.
Which ones the prime number 12 96 5 1?
5
How many positive prime numbers have a ones digit of 5?
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.
What digit is in the ones place in this number 12.534?
The digit 2 is in the ones place
what is less than 100 with a 1 in the units place are prime number?
2, 3, 5, and 7 are prime numbers for one digit numbers. 1 is NOT a prime number.
Is the thousandths place smaller or larger than the ones place?
Larger. See which number is larger 1,000 [Thousands place] or 1 [Ones place]
is the number 1 a prime number?
no 1 is not a prime number
What if a number has a 4 in the tens place a 1 in the tenths place a zero in the hundredths place and a 9 in the ones place so what is the number?
49.10
Could a number be both prime and composite if so which ones?
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.
Why is 336 not a prime number?
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)
