Show Solution
Identify where the numbers first differ by comparing place by place
1,234,567 vs others: differs at ten-thousands (2 vs 4) or thousands/lower places
1,243,567 has 4 in ten-thousands, others have 2, so it's largest
Among remaining three with same ten-thousands (2): 1,234,567, 1,234,576, 1,234,657
Compare hundreds place: all have 4, so check tens place
Tens place: 6, 7, 5 respectively
Order the three: 1,234,567 (6), 1,234,576 (7), 1,234,657 (5)
Final ascending order: 1,234,567 < 1,234,576 < 1,234,657 < 1,243,567
