Compare the digits in each place from left to right.
Start with the ten thousands place.

The digits in the ten thousands place are equal, so compare the digits in the thousands place.

The digits in the thousands place are equal, so compare the digits in the hundreds place.

The digits in the hundreds place are equal, so compare the digits in the tens place.

The digits in the tens place are equal, so compare the digits in the ones place.

Since 2 < 3, 61,242 < 61,243.

First, compare the digits in the hundreds place of each number.
2 is less than 6, so 256 and 265 are less than 652.

Next, compare the digits in the tens place of 256 and 265.
5 is less than 6, so 256 is less than 265.

256 is less than 265, which is less than 652.
So, the numbers in order from least to greatest are 256, 265, 652.
