x + 3 + 4x = 13 3 +5x = 13 -- combine like terms 5x = 10 -- subtract 3 x = 2 --- divide by 5 "x" equals two
39/1
39 - 1 = 38
Prime factors are 2, 2, 3, 3, 3, 13 (Other) Factors are combinations of the above, i.e. 2 x 2 = 4 2 x 3 = 6 2 x 13 = 26 3 x 13 = 39 2 x 2 x 3 = 12 2 x 2 x 13 = 52 2 x 3 x 3 = 18 2 x 3 x 13 = 78 3 x 3 x 13 = 117 2 x 2 x 3 x 3 = 36 2 x 2 x 3 x 13 = 156 2 x 3 x 3 x 13 = 234 3 x 3 x 3 x 13 = 351 2 x 2 x 3 x 3 x 3 = 108 2 x 2 x 3 x 3 x 13 = 468 2 x 3 x 3 x 3 x 13 = 702
117 = 3 x 3 x 13. It is: 3^2*13 = 117
3 = 3 13 = 13 14 = 2 x 7 LCM = 2 x 3 x 7 x 13 = 546
117 = 3 x 3 x 13
117 = 3 x 3 x 13
3 x 3 x 11 x 13 x 13
3 x 3 x 13 x 13As a product of its prime factors: 3*3*13*13 = 1521
2 x 13 = 26 3 x 13 = 39 2 x 3 x 13 = 78 2 x 11 x 13 x 13 x 71 = 263978
28561/13=2197 2197/13=169 169/13=13 answer: 13 to the 4th power
