If you are wanting to add odd numbers to get 399, it won't work. If you are wanting to multiply to get 399, it is 19 x 21.
Well, let's see here. To figure out how many times 31 goes into 399, we can simply divide 399 by 31. When we do that, we find that 31 goes into 399 about 12 times with a remainder of 7. Isn't that just a happy little reminder that numbers can be divided in different ways?
7x3 = 21 All numbers from 1-400 (399 total) that are factors of 21: 399/21 = 19

If you are wanting to add odd numbers to get 399, it won't work. If you are wanting to multiply to get 399, it is 19 x 21.
399*1 = 399. So 399 is divisible by 399. 399*2 = 798. So 798 is divisible by 399. 399*3 =1197. So 1197 is divisible by 399. 399*4 = 1596. So 1596 is divisible by 399.
The numbers are sqrt(399+1) ± 1 = 20 ± 1 = 19 and 21
No. 399 is not evenly divisible by two.
GCF(187, 399) = 1, the two numbers are coprime.
399 is not prime as it has more than two factors which are 1 and itself as it has many other combinations of numbers to resolve the question so no 399 is not prime

7 will go into 399 57 times with no remainder. So 399 divided by 7 is 57.

There are 99 of them ... all the numbers you say as you count from 301 to 399.
The Least Common Multiple (LCM) of 21 and 57 is 399.
