How to divide I2 and 4o by short division?

2 |40 12, 2 |20 6, 2 | 10 3 has no short divisor, so it is replaced by a vertical line. The least common multiple is 2*2*2=8.

Short division is a method to find the greatest common factor and can also be used to find the least common multiple. The method of finding the greatest common factor of several numbers begins with observation and comparison, that is, first find out the factor of each number, then find out the common factor, and finally find out the greatest common factor in the common factor. After that, the factorization prime factor method is used to decompose the factors of two numbers respectively, and then the operation is carried out. Then it evolved into a short division. The method of short division is to divide the divisor by the prime number divisible by it, and so on until the quotient is a prime number.
