To determine which number has the least value, we can compare the coefficients in scientific notation.
In scientific notation, the number is written as a coefficient multiplied by a power of 10.
For the given numbers:
86,659,000 = 8.6659 × 10^7
867,450,000 = 8.6745 × 10^8
86,423,000 = 8.6423 × 10^7
Comparing the coefficients, we can see that 8.6423 is the smallest.
Therefore, the number with the least value is represented in scientific notation as D. 8.6423 × 10^7.
