20 and 28 both have six factors.
They ARE the same.
The one digit number that has the same number of factors as the number six is three. Six's factors are 1, 2, 3, and 6 while three's factors are 1 and 3. Therefore, both numbers have the same number of factors.
if you mean what is an odd number whose has the same number of factors as the number itself... then 1 will work.
The proper factors of a number do not include one and the number itself.
The set of proper factors does not include 1 and the number itself.
187 will have the same number of factors no matter what you do to it.
No two numbers have the exact same factors.
Proper factors don't include one and the number itself.
Prime factorizations are unique. No other number will have exactly the same number of prime factors as 28. Multiples of 14 will have some of the same factors.
