There are five consecutive odd numbers whose product is 328 185. Find these five natural numbers

There are five consecutive odd numbers whose product is 328 185. Find these five natural numbers

Decomposition quality factor
328185=3*3*3*5*11*13*17
=(3*3)*(3*5)*11*13*17
=9*11*13*15*17
So these five numbers are 9, 11, 13, 15, 17

If the product of five consecutive odd numbers is 6194475, what are the five natural numbers

6194475=3*3*3*3*5*5*7*19*23
=19*(3*7)*23*(5*5)*(3*3*3)
=19*21*23*25*27
So these five natural numbers are 19, 21, 23, 25, 27

The product of multiplication of two natural numbers greater than 1 must be ()
A. Odd B. even C. prime D. composite

According to the analysis, the product of multiplication of two natural numbers greater than 1 must be a composite number. For example, 2 × 3 = 6, 6 is a composite number; 3 × 5 = 15, 15 is a composite number
