The prime factors of 20 are: 2 and 5.
The positive integer with only one factor is 1.
A prime number has two positive integer factors, itself and 1. The number 0 has no positive integer factors, and is therefore not prime. The number 1 has just a single positive integer factor, and once again, is not prime.
No, 5 is.
5 is a prime factor of both numbers.
A prime number is a number with two positive integer factors, while a composite number has more than two positive integer factors. Since the number 0 has no positive integer factors, and the number 1 has just one positive integer factor (itself), neither of these are prime.
The positive integer with only one factor is 1.
A factor of a integer is an integer that divides the second integer into a third integer exactly; i.e. A is a factor of B if B/A is exactly C, where all of A, B and C are integers. A prime factor is a factor as above, but is also a prime number. This means that the only factors of that factor are one and the number itself; i.e. A is a prime factor of B if B/A is exactly C andthe only factors of A are 1 and A.
No. Most integers aren't prime.
2, 3 and 5
No, 20 isn't prime.
what number is not a prime factor
1 and 41 because it's a prime number
4 is a prime factor of 20 whereas it isn't a factor of 50.
A prime number has two positive integer factors, itself and 1. The number 0 has no positive integer factors, and is therefore not prime. The number 1 has just a single positive integer factor, and once again, is not prime.
Since 13 is a prime number, its only positive integer factors are itself and 1. Since the number 20 shares the common factor 1, the only common factor of the numbers is 1.
The number 32 has only one prime factor: 2The true prime factor for any number is 1.
5 is the greatest prime factor of 20.
