What two digit number has two one digit factors that have the sum of 16 and the difference of 2?
63.
Let the smaller factor be n-1.
Then with a difference of 2, the larger factor is (n-1) + 2 = n+1
The sum of these is:
(n-1) + (n+1) = 2n = 16 ⇒ n=8
Thus the factors are
- 8-1 = 7
- 8+1 = 9
and the number is 7x9 = 63.
(The complete list of factor pars for 63 is: 1 & 63, 3 & 21, 7 & 9.)
Alternatively, if you don't want the simultaneous equations "hidden":
Let the two factors be x & y (so that the number is xy) with x bigger than y. Then
- x + y = 16
- x - y = 2
Adding the two equations gives:
2x = 18
⇒ x = 9
and substituting in equation 1 gives:
9 + y = 16
⇒ y = 7
and substituting in equation 2 to check:
9 - 7 = 2 as required.
So the factors are 7 & 9 and so the number is xy = 7x9 = 63.

What is a one digit number that has the same number of factors of the number six?
The one digit number that has the same number of factors as the number six is three. Six's factors are 1, 2, 3, and 6 while three's factors are 1 and 3. Therefore, both numbers have the same number of factors.
What is a two digit numbers times a one digit number to get 27?
To find a two-digit number multiplied by a one-digit number that equals 27, we can consider the factors of 27. The two-digit number must be 27 divided by a one-digit factor. The valid combinations are 27 = 9 × 3, where 9 is a one-digit number, and 27 divided by 3 gives us 9, which is also a one-digit number. Therefore, a valid two-digit number multiplied by a one-digit number to get 27 does not exist since 27 itself is a two-digit number.
Is there a number that only contains the single digit numbers as factors?
Sure. Any 1-digit number contains only one-digit numbers as factors. Any larger number, on the other hand, contains itself as a factor, so these can be excluded.

What is a two digit numbers times a one digit number to get 27?
To find a two-digit number multiplied by a one-digit number that equals 27, we can consider the factors of 27. The two-digit number must be 27 divided by a one-digit factor. The valid combinations are 27 = 9 × 3, where 9 is a one-digit number, and 27 divided by 3 gives us 9, which is also a one-digit number. Therefore, a valid two-digit number multiplied by a one-digit number to get 27 does not exist since 27 itself is a two-digit number.
