1 and 5.
The LCM of both numbers is 720
The HCF of both numbers is 1
One and nine will go into both numbers evenly
The numbers that go into 45 are 1, 5, 9, 45
The numbers 25, 27, and 45 can be broken down into their prime factors to find out what goes into them. 25 = 5 x 5 27 = 3 x 3 x 3 45 = 3 x 3 x 5 Therefore, the numbers that go into 25, 27, and 45 are 1, 3, 5, and 9.

Both 9 and 3 go into both numbers. 45/54 = 5/6 45/54 = 15/18
The numbers 25, 27, and 45 can be broken down into their prime factors to find out what goes into them. 25 = 5 x 5 27 = 3 x 3 x 3 45 = 3 x 3 x 5 Therefore, the numbers that go into 25, 27, and 45 are 1, 3, 5, and 9.
One will go into both numbers evenly
Both 9 and 5 go into 45, which is the least common multiple (LCM) of the two numbers. To find the LCM, you can list the multiples of each number (9: 9, 18, 27, 36, 45, ...; 5: 5, 10, 15, 20, 25, 30, 35, 40, 45, ...), and identify the smallest common multiple. Therefore, 45 is the smallest number that both 9 and 5 divide evenly into.
3 and 5 both go into multiples of 15, as both numbers are factors of 15. In mathematical terms, 15 is a multiple of both 3 and 5 because it can be evenly divided by both numbers without leaving a remainder.
