25 can be either the product of 1 and 25, or the product of 5 and 5. Since there are two digits in the number, the answer can only be 55. This makes sense, since 55 is divisible by 5, and the product of 5 and 5 is 25.
To find the fraction of 4-digit natural numbers with a product of their digits that is even, we first need to determine the total number of 4-digit natural numbers. There are 9000 such numbers (from 1000 to 9999). Next, we consider the conditions for the product of digits to be even. For a number to have an even product of digits, at least one of the digits must be even. There are 5 even digits (0, 2, 4, 6, 8) and 5 odd digits (1, 3, 5, 7, 9). Therefore, the fraction of 4-digit natural numbers with an even product of digits is 5/10 * 9/10 * 9/10 * 9/10 = 3645/9000 = 809/2000.
Three of them.
It means it is odd (ends in 1, 3, 5, 7, or 9), when you multiple the digits together you get 24 for an answer, and when you subtract the digits from each other you get 5. Hope this helps.
The only way to produce 4 as a product of digits is to have either a '4'or else '2 x 2' among the digits, and ' 1 ' for all the rest of them.Possibilities that include a '4':1111411141114111411141111. . . . . . . . . 5 possibilitiesPossibilities that include a pair of 2s :11122112121211221112112211212121121122112121122111. . . . . . . . . 10 possibilitiesTotal = 5 + 10 = 15 possibilities

5 of them.
You had me until "product." The product of 4 digits can't be prime.

There are seven digits: 8,000,000
Three of them.
3.1415 While true, pi to 5 significant digits is actually 3.1416!
In 1805 it was declared by Alex Norburtun that the first five digits of pi are 3.1415
When rounded to ten significant figures, the first ten digits of pi are: 3.141592654 The product of these digits is: 3 x 1 x 4 x 1 x 5 x 9 x 2 x 6 x 5 x 4 = 129600 Notwithstanding the eleventh digit of the number, which rounds the tenth digit 3 up to 4, the first ten digits of pi with 3 as the final number would be: 3 x 1 x 4 x 1 x 5 x 9 x 2 x 6 x 5 x 3 = 97200
There are 15 of them.
It can have up to 5 digits.
