The prime numbers from 1 to 100 are: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97. Why is 1 not a prime number? 1 is not a prime number because it has only one factor, namely 1. Prime numbers need to ...
Divide 400 by 9: 4009=44+, The largest prime number less than 44 is 43. Method 2 Since 9×40 is less than 400 and 9×50 is greater than 400, check the prime numbers between 40 and 50 . These prime numbers are :41,43, and 47 . Sin ce 9×41=369, 9×43=387, and 9×47=...
