Q. The integers m and p are such that 2<m<p and m is not a factor of p. If r is the remainder when p is divided by m, is r > 1 ?

1. the greatest common factor of m and p is 2

2. the least common multiple of m and p is 30

答案的确是A

请问一下有没有式子可以解释呢

我用例子来举是可以解A

但是在模考时，速度就很慢了

请大家帮忙解释一下

谢谢

问的是R是否大于1,而我理解成要算出R的值了.

根据条件1可以得初R大于1

而条件2不确定
