Lessons Mental arithmetic of the greatest common divisor

Summary of the program

Mental arithmetic of the greatest common multiple is the application and development of "Mental arithmetic of decomposition of numbers" in which the greatest common multiple is obtained by making use of decomposed numbers. For the reason, it is advisable to work on the greatest common multiple only after you have become good at "Mental arithmetic of decomposition" to some extent.

When you have become able to obtain the greatest common multiple mentally, a higher level of a sense of numbers will be developed. Way to go!

Abilities which can be developed
