Just multiply the first three prime numbers together.
4 and 5 5 and 6 6 and 7
Add them together, divide that total by three
There are multiple ways to add three numbers together to get a sum of 17. One possible combination is 5 + 6 + 6, another is 9 + 4 + 4, and yet another is 7 + 5 + 5.
5 and 10 10 and 15 5 and 15
It means write down three pairs of numbers that are relatively prime like 4 and 9, 5 and 6, 13 and 25
3 and 5, 4 and 6, 8 and 12
Just multiply the first three prime numbers together.
There are three pairs.
nine (Three pants per blouse; 3 x 3 = 9.)
Ruggieri and Ugolino
81 has three factor pairs: 81,1 27,3 9,9
The number 18.
81 As there are no limits stated then you can have a number comprising a repeated single digit (such as 2222), two pairs of numbers (e.g. 2244) or three different numbers (such as 2462). The first digit can be one of any of the 3 numbers. The second digit can be one of any of the three numbers, as can the third digit and also the fourth. Then you can have 3 x 3 x 3 x 3 = 81 different 4-digit numbers using the three given numbers.
One, two, and three.
5+2 6+1
The two numbers that have a product of 12 are 3 and 4. This is because 3 multiplied by 4 equals 12. These two numbers are factors of 12, as they can be multiplied together to result in the product of 12.
