There are an infinite number of them.
If you're only interested in positive, whole numbers, then there are 8 of them:
1, 2, 4, 5, 8, 10, 20, and 40.
Eleven.
40, 80, 120, 160, 200 +40 . . .
It is 1
Not as a whole number because 1/40 = 0.025
2..
The gcf is 8
40/8=5
Forty does not go into eight any whole number of times, as 40 is larger than 8. If you divide 8 by 40, the result is 0.2, indicating that 40 goes into 8 a fraction of a time. Thus, you could say that 40 goes into 8 zero times in whole numbers.
40 and 63 have no common prime factors.
To find out how many times 40 can go into 300, you divide 300 by 40. This calculation gives you 7.5. Therefore, 40 can go into 300 a total of 7 full times, with a remainder of 20.
2000 ÷ 40 = 50
40 times.
