最小公倍数是指两个或多个数共同拥有的公共倍数中最小的那个数。要找到63和12的最小公倍数,需要先找到它们的所有倍数,也就是63的倍数和12的倍数。分别列出它们的倍数如下:
63的倍数:63,126,189,252,315,378,441,504,567,630,693,756,819,882,945...
12的倍数:12,24,36,48,60,72,84,96,108,120,132,144,156,168,180,192,204,216,228,240,252,264,276,288,300,312,324,336,348,360,372,384,396,408,420,432,444,456,468,480,492,504,516,528,540,552,564,576,588,600,612,624,636,648,660,672,684,696,708,720,732,744,756,768,780,792,804,816,828,840,852,864,876,888,900,912,924,936,948,960,972,984,996,1008,1020,1032,1044,1056...
然后找到它们共同拥有的倍数,并从中找出最小的数。在上面的列表中,63和12共同拥有的倍数是 12,24,36,48,60,72,84,96,108,120,132,144,156,168,180,192,204,216,228,240,252,264,276,288,300,312,324,336,348,360,372,384,396,408,420,432,444,456,468,480,492,504,516,528,540,552,564,576,588,600,612,624,636,648,660,672,684,696,708,720,732,744,756。其中最小的是756,因此63和12的最小公倍数是756。
需要注意的是,最小公倍数存在一个简便的计算方法,即用两个数的乘积除以它们的最大公约数。这个方法可以更快地计算出它们的最小公倍数。
