there are infinite amount of answers...
first 10 multiples of 5 are 5, 10, 15, 20, 25, 30, 35, 40, 45, 50
first 10 multiples of 8 are 8, 16, 24, 32, 40, 48, 56, 64, 72, 80
8 and 48 are two possible answers.
The multiples of 10 are: 1, 2, 5, 10 The multiples of 5 are: 1 and 5. The multiples of 6 are: 1, 2, 3, and 6. The multiples of 8 are: 1, 2, 4, and 8. The number that they all have in common is 1, so the lcd is one.
Any multiple of 15.
The factors of 5 are 1 and 5. Neither is a multiple of 8.
Do you mean 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12? Do you want multiples of each one separately? e.g. multiples of 2, multiples of 3, multiples of 4? The answers to the times tables will do it if that is what you want. eg 2, 4, 6, 8, 10... 3, 6, 9, 12, 15... 4, 8, 12, 16, 20... etc.
The Least Common Multiple (LCM) for 5 and 8 is 40.
5
The last five multiples of 8 are 40, 32, 24, 16, and 8.
2, 4, 6, 8, 10, 12
7, 14, 21, 28, 35
8, 16, 24, 32, 40.
8, 16, 24, 32, 40
