The number at the midpoint of these two numbers is (15 + 27)/2 = 21
3(5-x) = 27 15 - 3x = 27 15 - 3x + 3x = 27 + 3x 15 = 27 + 3x 15 - 27 = 27 - 27 + 3x -12 = 3x -4 = x To check 3(5- -4) ? 27 15 - -12 ? 27 15 + 12 = 27

That number is 9.
It is 3 which is the HCF
This is in its simplest form. There is no number that goes in to both 27 and 70.
3 will go into both 15 and 27. 1 will go into any number, so also 1.
1 and 3
1 and 3
Only the number one (1) goes evenly into both 25 and 27.
3
In fact, 1 is the only whole number that evenly goes into both numbers.Answer 1' 1 ' does.
27 is 3 to the 3rd power, and 64 is 2 to the 6th power, so the only number that goes into both evenly is one (1).
All multiples of the lowest common multiple of 15 and 27 are in both their times tables. The lcm of 15 and 27 is 135, so all multiples of 135 are in both the 15 and 27 times tables: 135, 270, 405, 540, 675, 810, 945, 1080, 1215, 1350, ...
