The MCD e mcm (Greatest Common Divisor and Least Common Multiple) are fundamental concepts in mathematics, particularly in number theory. This guide provides a spiegazione semplice (simple explanation) of how to calculate these values using prime factorization and the Euler-Venn diagram method.
Least Common Multiple (m.c.m):
- To find the mcm, decompose numbers into prime factors
- Multiply common and non-common factors, taken once, with the highest exponent
- Alternatively, list multiples of both numbers and select the smallest common one
Greatest Common Divisor (M.C.D):
- For MCD, also decompose numbers into prime factors
- Multiply common factors, taken once, with the lowest exponent
- Another method is to list divisors of both numbers and choose the largest common one
The guide emphasizes the use of the Euler-Venn diagram as an alternative method for both calculations.
