To find the least common multiple (LCM) of 7 and 12, we can use the method of listing out the multiples or utilizing the formula involving the greatest common divisor (GCD).
The multiples of 7 are:
- 7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, 84, 91, 98, 105, 112, 119, 126, 133, 140, ...
The multiples of 12 are:
- 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144, ...
The first common multiple is 84.
Thus, the least common multiple of 7 and 12 is 84.
So the correct response is:
84

To find the least common multiple (LCM) of 3 and 9, we can note that 9 is a multiple of 3.
The multiples of 3 are:
- 3, 6, 9, 12, 15, ...
The multiples of 9 are:
- 9, 18, 27, ...
The smallest multiple that appears in both lists is 9.
Therefore, the least common multiple of 3 and 9 is 9.
So the correct response is:
9

To find the least common multiple (LCM) of 8 and 10, we can list out the multiples or use the prime factorization method.
Multiples of 8:
- 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, ...
Multiples of 10:
- 10, 20, 30, 40, 50, 60, 70, 80, ...
The smallest common multiple from both lists is 40.
Thus, the least common multiple of 8 and 10 is 40.
So the correct response is:
40
