All multiples of 39, which is an infinite number.
3,2,5,6,9,10
Because it is divisible by numbers other than 1 and itself. 39 is divisible by 1, 3, 13, 39.
37 39 54 ....... 159...................
38 isn't ( it's divisible by 2 )
There are 39 natural numbers between 1,000 and 1,500, inclusive, that are divisible by 13.
All real numbers are divisible by four. However, no numbers with decimal extensions are evenly divisible by four. The only numbers evenly divisible by four between 30 and 39 are 32 and 36. Otherwise, including decimals, there would be an infinite number of rational numbers between those limits divisible by four, and infinitely more than that if the real numbers are included (numbers that cannot be represented by terminating or repeating continued decimal expansions).
To show that the product of 56 and 39 is exactly divisible by 21, you can check if both numbers are divisible by the prime factors of 21, which are 3 and 7. Since 56 is divisible by 7 (56 ÷ 7 = 8) and 39 is divisible by 3 (39 ÷ 3 = 13), their product will also be divisible by both 3 and 7. Therefore, 56 x 39 is divisible by 21.
It is an endless list. 13, 26, 39 etc...
