Let x be the smallest number to be solved:x + (x+1) + (x+2) = 1233x + 3 = 1233x = 123 - 3 = 120x = 120 / 3 = 40 is the smallest numberand 40 + 41 + 42 = 123
123
The number itself.
the answer is 72 because 1 *72=72 so therefore we say that 72 is a multiple of 72 as well as the smallest multiple
Only the number 1 goes into both 43 & 123... because 43 is a prime number.
