Any multiple of 30.
The least common factor of 30 and 42 is the smallest number that is a factor of both of them and is 1.However, I suspect that you mean either:What is the highest common factor of 30 and 42?ie what is the highest number that is a factor of both 30 and 42: hcf = 6;What is the lowest common multiple of 30 and 42?ie that is the smallest number that is a multiple of both 30 and 42 lcm = 210.
The number that is a factor of 30 and a multiple of 2 is 2. A factor of a number divides it evenly without leaving a remainder, and in this case, 2 is a factor of 30 because 30 divided by 2 equals 15. Additionally, since 2 multiplied by 15 equals 30, 2 is also a multiple of 30.
No, 30 is a multiple of 15.
Yes, but only in one circumstance. A number is both a factor and a multiple of itself.Examples:8 is a factor and a multiple of 8. The factors of 8 are 1, 2, 4, and 8. The multiples of 8 are 8, 16, 24, 32, 40, ...13 is a factor and a multiple of 13. The factors of 13 are 1 and 13. The multiples of 13 are 13, 26, 39, 52, 65, ...30 is a factor and a multiple of 30. The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30. The multiples of 30 are 30, 60, 90, 120, 150, ...
There is no such number. If a multiple of 4 is a factor of 30, then 4 must also be a factor of 30, but 4 is not a factor of 30 (the factors of 30 are: 1, 2, 3, 5, 6, 10, 15, 30), thus no such number exists.

30
There is no answer. There cannot be a lowest common multiple of a single number, such as 30, because "common multiple" means a multiple that two or more numbers have in common. Likewise, there cannot be a highest common factor of a single number, such as 3, because "common factor" means a factor that two or more numbers have in common.
The answer is 9. It is a multiple of 3. 3+3+3=9. It is less than 20: 20-9=11.It is not a prime number. It is odd, and it is not a factor of 30. 30/9=3.3333333333
