1 and 19.
Ok, so 1 goes into 40 and 194 evenly, so does 2. Hope this helps!
19/40 is in the reduced form as there is no whole number that divides 19 and 40 evenly (remainder zero).
470 / 40 = 11.75. So 40 goes into 470 11.75 times, or if you are looking for how many times evenly, then 40 goes into 470 evenly 11 times.
It is: 1
19 and 2
2 and 10 go into 40 and 50 evenly.
1, 2, 19, 38.
1, 7, 19, 133.
Fifty-seven divided by three is 19, therefore three goes in evenly. If it goes in evenly, it is divisible.
