240 480 720 960 1,200 1,440 1,680 1,920 2,160 2,400
and so on ...
15 and 16 are both composite numbers
15 and 5 both go into every multiple of 15 .
16 and 13 both go into any multiple of 208 .
x + 16 < 15 x + 16 - 16 < 15 - 16 x < -1
Both 15 and 20 can go into 60, as they are both factors of that number.
16/15 = 1.066... ≈ 1.1
They both go into 90.
240 ÷ 16 = 15
11 and 15 both go into 165. 165 is the LCM (Least Common Multiple) of 11 and 15.
63 ÷ 16 = 3 with remainder 15
15 divided by 16 equals 0.9375
It was 16 for a very long time, but now you have to be 15.
