Writing a third-grade math tabloid involves decomposing a composite number into prime factors, usually by short division. Divide this complex number by a prime number until the quotient is a prime number, and then write the divisor and quotient in the form of multiplication.

The way to find the greatest common divisor of several numbers is to divide them continuously until the quotient obtained is only the common divisor of 1, and then multiply all the divisors to get the product, which is the greatest common divisor of these numbers.

The method of the least common multiple of several numbers is to divide the common divisor of these numbers (or part of them) until it is coprime (or pairwise coprime), and then multiply all the divisors and quotients to get the product, which is the least common multiple of these numbers.

Two numbers that become coprime relations: 1 and any natural number coprime; Two adjacent natural numbers are coprime; When the composite number is not a multiple of the prime number, the composite number and the prime number are coprime.

When the common divisor of two composite numbers is only 1, these two composite numbers are coprime. Interesting mathematics is a kind of interesting knowledge which integrates knowledge and interest. It is necessary to guide children with authoritative mathematical thoughts and unique ways of thinking, so that children can learn in fun and make progress in happiness. Let's understand the charm of interesting mathematics through handwritten newspaper and draw a simple and beautiful handwritten newspaper of interesting mathematics.
