No. Calculator is not needed.
17, 11, 13, and 7 are all prime numbers. They are already the prime factors of the product.
A prime number is a number that can be divided evenly by 1 or itself.
17 ÷ 1 = 17 ; 17 ÷ 17 = 1 *prime number
11 ÷ 1 = 11 ; 11 ÷ 11 = 1 *prime number
13 ÷ 1 = 13 ; 13 ÷ 13 = 1 *prime number
7 ÷ 1 = 7 ; 7 ÷ 7 = 1 *prime number
Prime factorization is finding which prime numbers multiply together to make the original numbers. Since the prime factors have been given, using a calculator to multiply the prime factors to find the prime factorization is no longer needed.
