prime factors of 60 = 2 * 2 * 3 * 5 and of 23 = 23 (23 is a prime number)
1, 5, 23, 115
The factors of 115 are: 1, 5, 23, 115
As 23 is a prime number, it has only two factors, the number one and itself. The factors of 23 are: 1 23 The prime factors are: 23 is a prime number.
3 x 5 x 23 = 345
It has an infinite number of factors, but it has four prime factors. 40 = 23 x 5
Since 115 ends in five, it will divide by '5'. Hence '5' is one of the factors. 5)115 = 23 Hence '23' is the other factor. Since '23' is a prime number, there are no other factors for 115 , but 5, and 23. except '1' & 115'.
Factors of 5: 1, 5.Factors of 23: 1, 23.GCF (5, 23) = 1
Positive factors of 23: 1, 23 23 is a prime number.
21 = 3 x 7, so it is not a prime number. 23 = 1 x 23, it does not have any other factors, so it is a prime number. 25 = 5 x 5, so it is not a prime number.
5 is. 23 isn't.
