Answer 1

`40|2\\20|2\\10|2\\.\ 5|5\\. 1|\\\\40=2\cdot2\cdot2\cdot5\\\\Factors:1;\ 2;\ 2\cdot2=4;\ 5;\ 2\cdot2\cdot2=8;\ 2\cdot5=10;\ 2\cdot2\cdot5=20;\ 40\\\\Answer:\boxed{1\&40;\ 2\&20;\ 4\&10;\ 5\&8}`

Answer 2

If you want you can do what i do.
first find all the numbers divisible by 40 in order. which would be:
1 2 4 5 8 10 20 40.
if you write it down you can make a rain bow and connect the first number to the last number. and so on. so the pair factors of 40 would be. 1&40 2&20 4&10 & 5&8
