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
