To determine the least value among these numbers, we need to convert them into scientific notation.

123,893 = 1.23893 * 10^5
31,892 = 3.1892 * 10^4
12,786 = 1.2786 * 10^4

Comparing the exponential values, 10^4 is the least among them. Therefore, the number 12,786 has the least value in scientific notation.
