What can you multipy to get 105?

Answer 1

105 is divisible by 5 because it ends in a 5.

105/5 = 21, so

5*21=105.

Since 21 = 3*7, and 5*3=15 and 5*7=35,

15*7 = 105 and

35*3 = 105 too.

Also, 105 * 1 = 105.

210 * 1/2 = 105,

315 * 1/3 = 105, etc.

Here I multiplied 105 by 2 or 3 and then multiplied back by 1/2 or 1/3.
