My approximation for cofactors with 90-110 digits - to be taken with a large pinch of salt as it is only based on some 200 examples so the deviation from the actual expectation is likely to be large...

Having done a bit of counting and calculation I've come to the conclusion that increasing the size of the number of digits doesn't actually make a significant difference to these probabilities. Yes,...

Curtis- I can have a go at the weekend - too much RL before then. The key in all the probabilities is the distribution of the number of factors - how likely it is to have 1, 2, 3 etc factors (other...
