No they do not, take a big Prime number and compare it to a smaller composite number. The number 6833 as only two factors (divisors), namely 1 and itself. But the number 68 which is much smaller has more factors or divisors. 68 has 2 and 4 and 17 and 1 and itself which is already more divisors than 6833.

The divisors of 26 are the numbers that can divide 26 without leaving a remainder. In this case, the divisors of 26 are 1, 2, 13, and 26. This is because 1 and 26 are always divisors of any number, and 2 and 13 are the other pairs of numbers that multiply to give 26.
31,37 are not composite
well look at the decimals if the first is bigger than its usally bigger the more numbers the smaller it is
Not necessarily. 73 has far fewer prime factors than 72.
Perfect numbers are numbers where all the factors add to that number. For example 6's factors are 1,2, and 3 and 1+2+3=6. Therefore the next perfect number isn't until 28 which is 1,2, 4, 7, 14 where 1+2+4+7+14= 28 An almost perfect number is a number which, when adding all of its proper divisors (all divisors except himself), gives you one less, or one more then the number itlself. Up to now all known almost perfect numbers are 2^n. So to answer your question, the 2 almost perfect numbers between 5 and 20 are 8 and 16. Divisors of 8: 1,2,4 -----> 1+2+4=7 Divisors of 16: 1,2,4,8 -----> 1+2+4+8=15
