My 6th grade algebra taught us to do the following:
6 12 18 24 30
8 16 24 32 40
Obviously I was naming multiples, and the lowest matching number is 24.
The easiest way to probably do this is to go through the times table of seven in your head and find anything similar numbers in the 6's multiplication table.6: 6,12,18,24,30,36,42,7: 7,14,21,28,35,4242 is the first number that comes in both of the tables. Therefore the least common multiple of seven and six is 42.
2, 4, 6 3, 6 The LCM of 2 and 3 is 6.
Since 6 is a multiple of 3, all of the numbers in the 6 times table will be contained in the 3 times table.
The least common multiple, or LCM, is the smallest integer that all the members of a given set of numbers will divide into evenly with no remainder. The least common factor of any set of positive integers is 1.
Numbers for which the sum of the digits is divisible by 9. This is also true for 3. There are other divisibility/multiple tests for other numbers (e.g., numbers that are divisible by 5 end in 5 or 0; numbers whose last two digits are divisible by 4 are divisible by 4)
