60 120 180 240 300 360 420 480 540 600 660 720
1 x 70 = 70
2 x 70 = 140
3 x 70 = 210
There is no number that I can find occurring in all three tables.
3 x 20 = 60.
Both ! 240 = 40 x 6 OR 60 x 4.
the numbers in the 4 times tables up to 12 are: 4,8,12,16,20,24,28,32,36,40,44, and 48the numbers in the 5 times tables up to 12 are:5,10,15,20,25,30,35,40,45,50,55, and 60
55 and its multiples. 1, 5, and 55 are all in both the 5 times and 11 times tables.
15, 30, 45, 60 and so on.
I can find 13 ways, not just 7, to make 60 from adding numbers in the 4, 5 and 9 times tables.
12, 24, 36, 48, 60 . . .
