For this case, we have that by definition, the minimum common multiple of two or more natural numbers, is the smallest natural number that is common multiplipo of the given numbers. Then:
[tex]8: 2 * 2 * 2 = 2 ^ 3\\12: 2 * 2 * 3 = 2 ^ 2 * 3\\\7: 7[/tex]
Taking the common and uncommon factors with their greatest exponent, we have to:
[tex]m.c.m = 2 ^ 3 * 3 * 7 = 8 * 3 * 7 = 168[/tex]
Answer:
168
