Multiples are used when we count by any number. Hence, multiples of 4 are, 4,8,12,16,20 etc. Students must quickly think: "oh, multiples, that means I'm counting by that number."

For example, for the numbers 3 and 4, the LCM is 12:<BR/>3x1=3<BR/>3x2=6<BR/>3x3=9<BR/>*3x4=12*<BR/><BR/>4x1=4<BR/>4x2=8<BR/>*4x3=12*<BR/><BR/>Similarly, "greatest common divisor" is the largest number that can divide *evenly* into two other numbers. For example, for 12 and 18, the greatest common SK19http://www.blogger.com/profile/17228027233405770851noreply@blogger.comtag:blogger.com,1999:blog-5639270444406781623.post-45854958925443361242007-07-13T14:15:00.000-07:002007-07-13T14:15:00.000-07:00I have been finding it difficut to explain the con...I have been finding it difficut to explain the concept of "least common multiple and the greatest common divisor" to my 11 years old kid. I would preferably want to explain it from practical application perspective. Suggestions would be very useful. Also your thoughts on the relationship between fractions and ratios.kchttp://www.blogger.com/profile/16602619615185178345noreply@blogger.com
