If you mean, "What is the largest number of digits possible in the product of two 2-digit numbers" then 99 * 99 = 9801, or 4 digits. Anything down to 59 * 17 = 1003 will have 4 digits.

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

52 is a number whose digits have a product of 10.

The 2-digit number must be 20, because it is the only 2-digit number whose sum of its two even digits, 2 + 0 = 2, is greater than the product of its two even digits, 2 x 0 = 0. Moreover, 20 is a product of the two consecutive integers 4 and 5.

67/72 of them.

When using significant digits, the product has only the number of significant digits as the lowest number in the factors. "20" has two significant digits and "310" has three. Therefore, the product has to have two significant digits. 310 Ã— 20 = 6200 6200 already has two significant digits.

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.

36 is twice the product of its digits multiplied. 3 times 6 equals 18, and 18 times 2 equals 36.

Impossible. With all multiples of nine the product of its digits is 9. Take, for exampe, 117 or 153.

No, while the first three digits of the product barcode may sometimesindicate where the product was manufactured, it will not alwaysdo so. For example, a barcode that has 690 as the first three digits indicates that the barcode was assigned by the Chinese EAN numbering authority. However, it does not necessarily mean that the product was actually manufactured in China.

There are two numbers that satisfy the criteria. 38 and 83
