A number is a multiple of 8 and a factor of 32. What is the number? A. 8 B. 16 C. 24 D. 32 相关知识点: 试题来源: 解析 A。8 的倍数有 8、16、24 等,32 的因数有 1、2、4、8、16、32,既是 8 的倍数又是 32 的因数的是 8,所以选择 A。
The 2 is a prime number, a number divisible only by 1 and itself. That means 2 is a prime factor of 32. A prime factor is a factor that is also a prime number. In other words, it's one of the smallest components of the number, and it can only be divided by 1 and by itself...
解析 C Do the prime factorization:1* 2* 3* 4* 5* 6* 7* 8* 9=1* 2* 3*(2* 2)*5*(2* 3)*7*(2* 2* 2)*(3* 3)Since there are seven factors of 2, the greatest power of 2 that is a factor is 2^7.反馈 收藏
