For an easy way to find the least common multiple of an array e.g. 8, 6, 42, 16, 32 follow the next steps: Divide each term of the array (gray column) by 2 see green row at top of the table, if the array item is not divisible by 2 write the number as is. Continue the process until all numbers that can be divided by 2 are 1, then start dividing by 3 and then by the next prime number. At the end multiply all the divisors at the top of the table (green row) to get the least common multiple. LCM = 2 • 2 • 2 • 2 • 2 • 3 • 7 = 672
