There are some apples. If you put them in a pile of 6, you will get one less. If you put them in a pile of 8, you will get seven more. The number of apples is about 50. How many apples are there?
The common multiple of 6 and 8 is 24, 48, 72
The number of apples is about 50
There are 48-1 = 47 apples
There is a pile of apples, if there are three, three, and the last two, if there are four, four, and the last three, if there are five, and the last four,
How many apples is there at least in this pile
Find the law
The multiple of 3 + the single digit of 2 may be 1 to 9, which is cycled every 30 digits
The multiple of 4 + the single digit of 3 may be 7 1 5 9 3, cycled every 20 digits
The number of multiples of 5 + 4 is only 9 or 4, which is cycled every 10 digits
From the multiple of 4 + 3, the single digit may be 7 1 5 9 3 and the multiple of 5 + 4, the single digit may only be 9 or 4 can only be 9
Find the final result according to the cycle
Multiple of 3 + 2: 29 59 89
Multiple of 4 + 3:19 39 59 79
Multiple of 5 + 4:9 19 29 39 49 59 69
The result was 59
The least common multiple minus one is the most scientific

1. The common factor of 3,5,7 is 3 * 5 * 7 = 105, the remaining 2,4,6 are less than 3,5,7 by 1, so 105-1 = 104. There are at least 104 apples in this pile. 2,1.36 M = 136 cm, 0.8 m = 80 cm, the maximum common factor of 136,80 is 8136 / 8 × 80 / 8 = 17 × 10 = 170, 170 can be cut
