The answer is 40.
50 + 40 + 40 + 40 + 30 + 30 + 20 + 10 = 260

10 + 10 + 10 + 10 = 40
I think you mean you want to pull the common factor(s) of 10 and 40 outside the expression 10 + 40. Since 40 is divisible by 10, 10 is clearly the gcf. So 10 + 40 = 10 * 1 + 10 * 4 =10 * (1 + 4).

10 plus 20 plus 30plus 40 plus 50 equals 150 because 50 plus 40 equals 90 plus 30 =120+20= 140 then + 10 = 150
