the answer would seem to be ten.
None. The LCM (least common multiple) is the smallest positive whole number exactly divisible by two or more whole numbers.
16 has five factors.
4096 is the smallest number with exactly 13 factors. (Including 1 and itself as factors).192 is the smallest number with exactly 13 properfactors, (excluding the number itself).120 is the smallest number with at least 13 factors (it has 16 factors)To find the smallest number with exactly N factors (for example, N=12):Factor N into primes, (for example, 12= 2*2*3Subtract 1 from each of the prime factors (for example, 1,1,2)Sort them by largest first (for example, 2,1,1)Raise successive prime numbers to these powers (for example, 2^2,3^1,5^1)Multiply these together (for example: 4*3*5 = 60; 60 is the smallest number with exactly 12 factors).
240 is the smallest number with at least 19 factors. 240 has twenty factors: 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240 262144 is the smallest number with EXACTLY 19 factors
The least common multiple of the numbers 12, 14 and 16 is 336.

None. The LCM (least common multiple) is the smallest positive whole number exactly divisible by two or more given whole numbers.You need at least two numbers to find the LCM.
LCM stands for Least Common Multiple, and is as its name suggests, the smallest factor, aside from 0 and 1, of multiple numbers. (LCM of 6 and 8 is 24, as factors of 6 are : 6, 12, 18, 24, 30, etc. Factors of 8 are: 8, 16, 24, 32, 40, etc. As 24 is the smallest number in these sequences, it is the Least Common Multiple, or LCM.)
There is no such thing as the smallest common factor. I guess the smallest common factor (integers only) for 16 and 24 would be -8. But that's just the negative version of the greatest common factor. I think you meant to ask either what is the smallest common multiple of 16 and 24 or what is the greatest common factor of 16 and 24. The greatest common factor of 16 and 24 is 8. The smallest common multiple of 16 and 24 is 48.
