x+(x+1)+(x+2)+(x+3)=42 4x+6=42 4x=36 x=9 answer: 9, 10, 11, and 12
42 and 55 have no common factor ((2 x 3 x 7) and (5 x 11)) so 42/55 is the simplest form.
22 = 2 x 11, 42 = 2 x 3 x 7, 51 = 3 x 17. So start with 22, then multiply factors that are not present, so the 2 is already present, and we have LCM of 22 and 42 = 2 x 11 x 3 x 7. Then with 51, the 3 is already present, so the answer is 2 x 11 x 3 x 7 x 17 = 7854

42,84,126,168,210,252,294,336,378,420,462,504lol
It starts: 1 x 42 = 42 2 x 42 = 84 3 x 42 = 126 4 x 42 = 168 5 x 42 = 210 6 x 42 = 252 7 x 42 = 294 8 x 42 = 336 9 x 42 = 378 10 x 42 = 420 11 x 42 = 462 12 x 42 = 504 ...
11 x 42 = 462

2 x 3 x 7 = 42 2 x 2 x 3 x 11 = 132
x+(x+1)+(x+2)+(x+3)=42 4x+6=42 4x=36 x=9 answer: 9, 10, 11, and 12
Unless there is a common factor, LCM is the product. 42 = 2 x 3 x 7; 66 = 2 x 3 x 11. There are common factors of 2 and 3 so one occurrence is to be ignored when multiplying ie 2 x 3 x 7 x 11 so LCM = 462 (11 x 42, 7 x 66)
31=7x-11, 31+11=7x, 42/7=x, x=6 :)
