To find the least common multiple (LCM) of 6 and 8, we need to list the multiples of each number:
Multiples of 6: 6, 12, 18, 24, ...
Multiples of 8: 8, 16, 24, ...
The smallest number that appears in both lists is 24, so the LCM of 6 and 8 is: 24
Use the formula: (a+b)^2=a^2 +2ab+b^2
(102)^2 =(100+2)^2
=10000+400+4
=10,404
