To do this problem, we need to list out the multiples of 45, 30, and 35.
00:07
So we'll start with the 45, and 45 times 1 is 45.
00:12
And i can just continue adding 45 over and over again to get a list of 45, multiples of 45.
00:20
So 90, and if i add 45, i get 135, and add 45, and i get 180, and add 40.
00:30
45 and i get 225 and add 45 and i get 270.
00:37
I'm just gonna make this list really long.
00:40
Add 45, 315, that way i don't have to keep coming back.
00:44
Add 45 360 and let's do a couple more.
00:48
Add 45, i get 405 and add 45 and i get 450.
00:56
So pretty good, i got a nice list here.
00:58
Let's try the other ones and hopefully we don't have to come back, but we might.
01:02
Let's try 30, so i get 30 times 1, and 30 times 2 is 60, and just keep adding 30 over and over again.
01:10
120, 150, 180, 210, 240, 270, 270, 360.
01:26
Okay, so we got the 30s there, and now 35.
01:29
35 times 1 is 35, 35 times 2, and just keep adding 30s.
01:35
35, 105, 140, 175, 210, 245, 280, 280, 315, 35, 285, 35, 285...
