20, because 15 divides by 5 is 3, And 3 times 8 is 24, And 24 minus four is 20.

No - neither number is a prime ! 42 divides by 2, 3 & 7 - and 93 divides by 3 !
Note that 20 exactly divides 40 because 40 / 20 = 2. Then, the GCD of 20 and 40 is 20.

Because 10 is a factor of 20 and 40. So any number which divides 10 evenly divides the factor of 20 or 40 evenly
Yes, because it divides into 51 with no remainder.
The factors of 60 are 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60.

The smallest prime number that evenly divides into 33 is 3.
Because...500 divides by 4 to give 125... 20 divides by 4 to give 5 and... 8 divides by 4 to give 2... making the result 132
No. 2 divides them both, for example.
Any non-zero number does.
