matlab求最大公约数和最小公倍数

最大公约数：（函数）

function n = zuidagongyueshu(a,b)
if(a>b)
    tem = a;
    b = a;
    a = tmp;
end
for i=1:a
    c = rem(b,a);
    if(c == 0)
        n = a;
        break;
    end
        b = a;
        a = c;
end

测试：

clc;
clear;
a = 8;
b = 22;
disp(\'最大公约数为：\');
zuidagongyueshu(a,b)

最小公倍数：（函数）

function n = zuixiaogongbeishu(a,b)
if(a>b)
    tem = a;
    a = b;
    b = tem;
end
n = 1;
for i = 1:a
    if(rem(a,i)==0&&rem(b,i)==0)
    n = n * i;
    a = a/i;
    b = b/i;
    end
end
n = n*a*b;
end

测试：

clc;
clear;
a = 12;
b = 9;
disp(\'最小公倍数是：\');
n = zuixiaogongbeishu(a,b)
