You put the four digit number at the top of the three digit number and you do the same thing as you would do with a two digit number with a 3 digit number.
60. There are 5 different choices for the first digit, four for the second digit, and three choices for the third digit. According to the fundamental counting principle, you multiply them together to get the total number of possible ways, and 5 x 4 x 3 = 60 Another way to think about it is 5!/3!

A three-digit number that is divisible by both three and four must also be divisible by their least common multiple, which is twelve. The smallest three-digit number divisible by twelve is 108, and the largest is 996. Therefore, any three-digit number that is a multiple of twelve, such as 120, 144, or 480, will meet the criteria of being divisible by both three and four.

The highest four-digit number using three odd digits is 9997. This is achieved by using the digit '9' three times (the highest odd digit) and the next highest odd digit, which is '7', to complete the four-digit requirement. Therefore, the combination of three '9's and one '7' results in the number 9997.
The smallest four-digit number not using zero is 1000. In a four-digit number, the first digit cannot be zero, so the smallest possible value for the first digit is 1. The remaining three digits can be any number from 0-9, so the smallest possible four-digit number is 1000.
I think you mean, the largest four digit number that has exactly three divisors. 2X3X1663=9,978
Well, friend, when you add two two-digit numbers together, the sum will always be a two-digit number or a three-digit number, not a four-digit number. It's like mixing different colors on your palette - you'll get a beautiful new shade, but it won't be something completely different. Just keep adding those numbers together and creating something wonderful!
