问题 What is the largest prime factor of 636?______

选项

答案53

解析 The correct answer is 53. The best way to determine the prime factors of a large number is to use a factor tree. Start with 636, and divide by any available prime factor: for instance, two factors of 636 are 2 and 318. Next, 318 is divisible by the prime number 3, leaving 106. Finally, 106 is divisible by 2, which leaves you with 53.
