What is the decomposition quality factor of 12? Is there a standard definition?

Decomposing prime factor refers to decomposing the original number with prime number. Prime number is only 1 and its two divisors, so the prime factor of 12 decomposing is 12 / 2 = 6,6 / 2 = 3.3, which is already prime number, so the prime factor of 12 decomposing is 2,2,3

18 = decomposition quality factor

Decomposition quality factor 18 66 102

18=2*3*3
66=2*3*11
102=2*3*17

1-3-5+7+9-11-13+15+17-.+999

Because there are a total of 1000 / 2 = 500 numbers, pairing them is just 250 groups
Among the 250 groups, 125 got 2, 125 got - 2, and the sum of - 2 got 0
（1-3）+（-5+7）+(9-11)+(-13+15)...+(-997+999)
=-2+2-2+2...-2+2
=0

The sum of one third and one fourth multiplied by a number equals seven eighths. What's the number
