The highest common factor is the greatest number which both numbers can divide by evenly. In this case, the greatest number 40 can divide by is 40. 80 can also divide by 40, and so this is a common factor. As no numbers greater than 40 will be able to divide 40 evenly, the hcf of 40 and 80 is 40.

Only 1 because 72 is a prime number which is a whole number greater than on two factors
Numbers less than zero are "negative numbers".
The problem asks the student to explain it. Not sure what to say other than answer it (it can be divided evenly by...)
The least common multiple (LCM) of a set of numbers is the smallest number into which each number in the set will divide evenly. There is no LCM for less than two numbers.
6. 1,2 and 3 divide evenly into it. And 1+2+3 = 6

-- Any number less than 124 can go into 124, but most of them can't go into it evenly.-- The numbers that go into 124 evenly are: 1, 2, 4, 31, 62, and 124.
The following numbers all meet that criteria:279288297306315324
