There are many possible answers. One quartet is
-1, -1, 1, 315
15 multiplied by 21 is 315.
315 degree
1,3,5,7,9,15,21,35,45,63,105,315
They are: 103+105+107 = 315
Only 315. To be divisible by 3 numbers have to add to a number divisible by 3 (3+1+5 =9). To be disable by 5, number has to end in a 5 or 0
63 & 5 21 & 15 9 & 35
To find the numbers, you can start with any factor pair of the number and keep factoring the composite numbers until all factors are prime. 315 3 x 105 3 x 3 x 35 3 x 3 x 5 x 7 = 315
(315,1)(105,3)(63,5)(45,7)(35,9)(21,15)
10 multiplied by 315 is 3,150.
315 multiplied by two is 630.
