The smaller is the rounding factor, the more accurate the estimation is
532668 rounded to the nearest ten is 532670
532668 rounded to the nearest hundred is 532700
532668 rounded to the nearest thousand is 533000
532668 rounded to the nearest ten thousand is 530000
532668 rounded to the nearest hundred thousand is 500000
We can use either 532700 or 533000 as a reasonable estimate because these values don't give much difference to the original value
