More than two, but it's not a set number.
30 has exactly 8 factors 1,2,3,5,6,10,15,30
Prime numbers have exactly two numbers. There is theoretically an infinite number of them.
The smallest is 192 but there are infinitely many such numbers. For example, take any prime number to the 13th power and the result will have exactly fourteen factors. The smallest is 192.
There are infinitely many such numbers. For example, take any prime number to the 11th power and the result will have exactly twelve factors.
A prime number is a positive integer that has exactly two factors - 1 and itself. A prime number has only two factors which are itself and one.
Every prime number has exactly 2 factors, 1 and the number itself.
2.
A number with exactly two factors is a prime number. Some examples are 2, 3, and 11. Note that 1 is not a prime number because it has one factor (1). Also, 0 is not prime because it has infinitely many factors (1, 2, 3, 4, 5, ...).
If you mean have exactly 6 factors then infinitely many!Including those with at least 6 factors makes no difference, there are still infinitely many.The number of factors of a number depends solely upon the prime factorisation of the number. There will be exactly 6 factors if the number:has a single prime to the power five (eg 32 = 2 x 2 x 2 x 2 x 2 = 25); oris the product of two primes, one of which is squared (eg 12 = 2 x 2 x 3 = 22 x 3; 50 = 2 x 5 x 5 = 2 x 52)As there is an infinite number of primes, there are an infinite number of numbers with exactly 6 factors.
Six factors.
There are three of them with exactly five factors.
The lowest prime number is two, because it is the smallest integer that divides by 1 and by itself and not by a third integer. You see, a prime number is a number that only has two factors, one and itself. Many people think one is the smallest prime number but no it isn't. It only has one factor not two factors so it is a perfect number. a prime has exactly two factors.
