32 x 19
45 = 32 x 51
23 x 53 = 1000
All numbers have factors. Some factors are prime numbers. A prime factor is a factor that is a prime number. A common prime factor is a prime factor that appears on the list of factors of two or more given numbers.
A factor can or cannot be a prime number Ex: 2 is the factor of all other even numbers its a prime number but 9 is a factor of 18 and its not a prime number A prime is a factor but a factor being a prime number varies
Exactly as it is because 31 is a prime number
Its factor are 1 and 19 because it is a prime number
Find out
32 x 19
2 x 5 = 10
write the prime factorization of 625
45 = 32 x 51
23 x 53 = 1000
18 9,2 3,3,2
22 x 3 = 12
3 x 13 = 39
17 is a prime and so has no factors other than 1 and itself. Therefore, in factor form, you get the tautological statement: 17 = 17
