To find the number with the least value, we need to compare the coefficients (the numbers before the multiplication sign) and the exponents (the numbers after the multiplication sign) in scientific notation.
Converting the given numbers to scientific notation:
86,659,000 = 8.6659 x 10^7
867,450,000 = 8.6745 x 10^8
86,423,000 = 8.6423 x 10^7
Comparing the coefficients, we see that 8.6423 is the smallest value.
Therefore, the number 86,423,000 has the least value in scientific notation: 8.6423 x 10^7.
