1+38 = 39
Just 37. 35 = 5 x 7 36 = 2 x 2 x 3 x 3 38 = 2 x 19 39 = 3 x 13
The answer is 672.
1 x 39, 3 x 13 = 39
58
19 x 39 = 741
19 with 1 remaining 39 - 1 = 38 = 2 x 19
19/5 = 19 1/2 19 1/2 = [(19 x 2) + 1] / 2 => [38+1] /2 39/2
In math, anything can equal 39. for example, x+40=39 if x= -1 and 13x=39 if x=3. Even the derivative of 39x is equal to 39.
39% of 19= 39% * 19= 0.39 * 19= 7.41
39 and 1 13 and 3
1+38 = 39
39-19 = 20
19% of 39 is 7.41
19 + 39 = 58
That first number was probably 39, but as written... 2 x 19 = 38 2 x 2 x 13 = 52 13 x 13 = 169 2 x 2 x 13 x 13 x 19 = 12844, the LCM If it was 39, the LCM would have been 2028.
