25 and 18 are a factor pair of 450 whose sum is 43.
5 + 2 = 7
To find the common factors of 9 and 18, we first need to list the factors of each number. The factors of 9 are 1, 3, and 9, while the factors of 18 are 1, 2, 3, 6, 9, and 18. The common factors of 9 and 18 are 1, 3, and 9. Adding these common factors together gives us a sum of 13.
Since 18 is a factor of 72, all of its factors are common.
It is not possible to express something as a sum of whole numbers with no common factor. All whole numbers have at least 1 as a common factor.
25 and 18 are a factor pair of 450 whose sum is 43.

18 and 81
18 & 81, 27 & 72, 36 & 63, 45 & 54 all fit the description.
To find the common factors of 9 and 18, we first need to list the factors of each number. The factors of 9 are 1, 3, and 9, while the factors of 18 are 1, 2, 3, 6, 9, and 18. The common factors of 9 and 18 are 1, 3, and 9. Adding these common factors together gives us a sum of 13.
Since 18 is a factor of 72, all of its factors are common.
2, 3, and 13 are all prime numbers and their sum is equal to 18.
Since 9 is a factor of 18, all of its factors are common (not cimmin).
The factors from greatest to least are: 11,11,5,3,3. The smallest prime factor is 3. You can get a quick idea of this by the fact that the digital root (number that goes evenly into the sum off all digits) is 18 which is divisible by 3.
There are 3 factor pairs of 18: 18 = 1 x 18 18 = 2 x 9 18 = 3 x 6
