公因數:
x = int(input("please input a number:")) y = int(input("please input a number:")) if x > y : c = x else: c = y for k in range(2, c): if x % k == 0 and y % k == 0: print(k)
結果:
please input a number:10 please input a number:20 2 5 10
最大公因數:
x = int(input("please input a number:")) y = int(input("please input a number:")) if x > y : c = x else: c = y for k in range(c, 2, -1): if x % k == 0 and y % k == 0: print(k) break
結果:
please input a number:10 please input a number:20 10
最小公倍數:
x = int(input("please input a number:")) y = int(input("please input a number:")) if x > y : c = x else: c = y m = (x + 1) * (y + 1) for k in range(c, m): if k % x == 0 and k % y == 0: print(k) break
結果:
please input a number:10 please input a number:20 20
