18 + 19 + 20 = 57
How about: 23+34 = 57
The numbers are 57, 59, 61 and 63.
The numbers are 56, 57 and 58.
The numbers are 57 and 59.
The sum of two evens is even so the sum of any number of evens is even. It is, therefore, impossible for the sum of three even numbers, whether or not consecutive, to be 57, which is an odd number.
Since 57/3 = 19, we know that the middle number has to be 19. The other numbers will be the numbers contiguous to 19. Therefore, the three consecutive numbers which add up to 57 are: 18 + 19 + 20 = 57
No.

x + y = 57x - y = 11Add: 2x = 68x = 34y = 57 - x = 23Check: 34 - 23 ?=? 11 ? Yes. yay !
The product is 1254. The sum is 79.
The sum of the first 57 natural numbers is 1,625.
