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.

One and nine will go into both numbers evenly
1, 5, 25.
The HCF of both numbers is 1
Both 9 and 3 go into both numbers. 45/54 = 5/6 45/54 = 15/18
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.
One will go into both numbers evenly
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.
Nine: 1 3 5 9 15 25 45 75 225
The hcf of both numbers is just 1
