440 and all of its multiples.
40
If you mean 11/40 then they are both equivalent
40 8x5=40 5x8 :/
11 and 15 both go into 165. 165 is the LCM (Least Common Multiple) of 11 and 15.
99
As 11 is prime, only 1 will go into both.
-40
The answer is 11, (11 x 3.5 = 38.5 with a remainder of 1.5)
40 and 63 have no common prime factors.
40 R 11
Twice... with a remainder of 11
13 times 11 = 143.So they both go into any integral multiple of 143.
