The digits product of two digit has number four
from 3 digits (10x10) to 4 digits (99X99)
67/72 of them.
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.
The answer is 4. You get the answer by trying the example of the largest two digit number, 99. 99 x 99 = 9801. This has four digits, so you can't get more digits than this by multiplying two two digit numbers. * * * * * True, but you CAN have fewer: 10*10 = 100, which is only three digits! 1490 of the 8100 2 digit x 2 digit multiples have products of 3 digits, the rest have 4 digit products.
There are two numbers that satisfy the criteria. 38 and 83
It should be obvious (it is, isn't it? am I expecting too much of today's educational system?) that the largest possible result of multiplying two two digit numbers is 99x99 = 9801, which has four digits, and the smallest possible result is 10x10 = 100, which has three digits.
They are 39 and 52.
1234, 2637, 7777, 2727 are examples of a four digit number. So any random four numbers are four digits.
There are 15 of them.
If the two decimal numbers have x and y digits after the decimal points, then the product has (x + y) digits after the decimal point.
There are a variety of three digits that add up to 25. Examples include 9, 8 and 8.
There are three such numbers: 12, 24 and 36.
They are: 1*2*3 = 6
The four numbers are: 113, 131, 151 and 191. For the product of the digits to be prime, the number must contain 2 ones - which greatly simplifies the exercise.
There are five such numbers: 11, 12, 15, 24 and 36.
Just multiply one pair of your numbers to give you a product, and then multiply their product by your third number.
If the question is about the product of all odd digits, the answer is 945. Otherwise the question does not make sense.
Try the different numbers - there are only 11 after all - and multiply their digits. Or analyze the factors of the number 21.
