There are none. 1 is the least divisor. 2 would be second least.
At least one other than 1 and itself. It can have infinitely many.
No, 35 is not a prime number. A prime number is defined as a number greater than 1 that has no positive divisors other than 1 and itself. Since 35 can be divided by 1, 5, 7, and 35, it has divisors other than 1 and itself, making it a composite number.
No, 21 is not a prime number. A prime number is defined as a natural number greater than 1 that has no positive divisors other than 1 and itself. Since 21 can be divided evenly by 1, 3, 7, and 21, it has divisors other than 1 and itself, making it a composite number.
10 = 2 * 5. It has divisors other than 1 and itself.
Least number with exactly n even divisors 1 -> 0 divisor 2 -> 1 divisor 4 -> 2 divisors = 22 8 -> 3 divisors = 23 12 -> 4 divisors = 22x3 32 -> 5 divisors = 24
31,37 are not composite
The prime numbers are numbers greater than 1 that have no divisors other than 1 and themselves. Out of the numbers 21, 23, 22, and 27, only 23 is a prime number because it is only divisible by 1 and 23 itself. The other numbers have divisors other than 1 and themselves, making them composite numbers.
A prime number (or a prime) is a natural number greater than 1 that has no positive divisors other than 1 and itself.
No, 39 has two positive divisors other than 1 and itself; 3 and 13.
A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. Among the numbers you listed—5, 15, and 25—only 5 is a prime number, as it can only be divided evenly by 1 and 5. In contrast, 15 and 25 have divisors other than 1 and themselves, making them composite numbers.
Numbers called relatively prime or mutually prime have no common factors or divisors other than 1. Numbers having any common factors or divisors greater than 1 are not relatively or mutually prime.
Yes, 15 is considered a composite number because it has more than two positive divisors. Specifically, its divisors are 1, 3, 5, and 15. Since it can be divided by numbers other than 1 and itself, it meets the definition of a composite number.
