5 and 10 do.
So do 1 and 14 .
1,3,5 and 15
527
315
Two factors of 30 are: 6 and 5; 3 and 10. An additional factor is: 2 and 15
5 is a positive common factor of 15 and 10
How about: 9+6 = 15
-273
575
-7585
-355
You can break them down and add the 15 and 30 to give 45, the 400 and 700 to give 1100 and then add those two totals together to get the final total of 1145.
factors of 30 that add to 17 are 2 and 15
-23
15 x -16 = -240 15 + -16 = -1
