The order of magnitude for numbers greater than 1 is 10 raised to the power of the number of digits before the first number.

In this case we have 67,432,944, which has 7 digits (7432944) before it's first number (6). Therefore the order of magnitude is `10^7`.

The number can be written as approximately `6.7 * 10^7`
