Let's convert each of the numbers into scientific notation and then compare them:
- \( 364,879 = 3.64879 \times 10^5 \)
- \( 436,765 = 4.36765 \times 10^5 \)
- \( 463,000 = 4.63 \times 10^5 \)
Now, when comparing the scientific notation, all three numbers are expressed with the same power of ten (\(10^5\)). Therefore, we can simply compare the coefficients:
- \( 3.64879 \)
- \( 4.36765 \)
- \( 4.63 \)
Among these, \( 3.64879 \) is the smallest coefficient. Thus, the number with the least value is:
364,879 (or \( 3.64879 \times 10^5 \) in scientific notation).
