To determine how many times the digit 4 appears in numbers from 1 to 623, we can consider the units, tens, and hundreds place separately. In the units place, the digit 4 appears once in numbers ending in 4 (4, 14, 24, ..., 614). This happens 62 times. In the tens place, the digit 4 appears 10 times in every hundred numbers (40-49, 140-149, ..., 540-549), so it appears 6 times within the range from 1 to 623. In the hundreds place, the digit 4 appears once in every hundred numbers (400-499), occurring 1 time. Therefore, the digit 4 appears a total of 62 + 6 + 1 = 69 times in numbers from 1 to 623.
