The common multiples of 15 and 27 are numbers that can be evenly divided by both 15 and 27. To find the common multiples, we need to identify the multiples of each number and then determine the numbers that appear in both lists. The multiples of 15 are 15, 30, 45, 60, 75, 90, etc., and the multiples of 27 are 27, 54, 81, 108, etc. The common multiples of 15 and 27 are numbers that appear in both lists, such as 45, 90, 135, etc.
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

The common factor of both 15 and 27 is 3.
That number is 9.
It is 3 which is the HCF
3 will go into both 15 and 27. 1 will go into any number, so also 1.
This is in its simplest form. There is no number that goes in to both 27 and 70.
1 and 3
Only the number one (1) goes evenly into both 25 and 27.

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, ...
