246 and 248.
Any even number can be written in the form 2n, for some integer n. The next consecutive integer is 2n + 2. These two numbers added together equal 494:
2n + (2n + 2) = 494
so
4n + 2 = 494
4n = 492
n = 123
so
2n = 246 and 2n +2 = 248.
490.
494
645 - 151 = 494 494 / 2 = 247 247 + 151 = 398 Which means: 398 + 247 = 645 and 398 - 247 = 151
494/1000 = 247/500
494 divided by 14 is 35 with remainder 4
490.
494 can be made by adding 246 and 248 together. In this case, 246 + 248 = 494. These two numbers add up to equal 494.
Prime numbers are numbers that can be divided by by only 1 and itself. 494 can be divided by 2, 247 etc. so it is not a prime number.
To find two numbers that multiply to 494, we can factorize 494 into its prime factors: 2 x 13 x 19. Since the factors of 494 are 2, 13, and 19, the two numbers that multiply to 494 are 13 and 38. Therefore, 13 x 38 = 494.
494
247, 494 (=247*2), 741 (=247*3) etc.
645 - 151 = 494 494 / 2 = 247 247 + 151 = 398 Which means: 398 + 247 = 645 and 398 - 247 = 151
39+38+...+1 = 39*38/2 = 494
494-219 = 275
494 is a composite number. A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 have a different name.
The factors of 494 are: 1 2 13 19 26 38 247 494
494, 495, and 496. One way to figure it: Let the 3 numbers be N, N+1, and N+2. So N + N+1 + N+2 = 3*N + 3. Set equal to 1485, and solve for N. N = 494. So the other two numbers are 495 and 496.
