A number in which 50000 of the hundreds are 6, 10 is 7, and the rest are 0. This number is written as (60570) and pronounced as (60570).

The distance between the earth and the sun is 1.492 million kilometers, and the number in units of "ten thousand" is (1.4920) million kilometers. If rounded to 100 million, it is about (1) million kilometers.

3009.39, from left to right, the first "3" means (three thousand) and the second "3" means (three tenths). This number is about (3009.4), with one decimal place reserved.

1, 2, 3, 4, 6, 9, 30, 57, 98, the odd number has (1 3 9 57) even number (2 4 6 30 98) composite number (4 6 9 30 57 98) prime number (2).

The factor of 20 is (1 245 1 20), and the multiple of 6 within 50 is (6 12 18 24 30 42 48).

If A=2×2×3×5 and B=3×3×5, then the greatest common factor of A and B is (15) and the smallest common multiple is (180).

The two prime numbers whose difference is 1 are (2) and (3), and their least common multiple is (6).

The two bits adjacent to the million bits are (10 million bits) and (10 million bits).

A number consists of four ones, eight tenths and four percent. This decimal is written as (4.84) and read as (4.84). Their counting unit is (0.0 1), and one decimal place is (4.8).

Prime numbers have only two divisors (correct)

12÷3=4, so 12 is a multiple and 3 is a divisor (error).

The divisor of a number is less than a multiple of this number (error)

Two prime numbers must be coprime, and the coprime of two numbers must be prime numbers (error).
