How is a number divisible by 7
WebThis program prints out all the numbers from 1 to 100 that are divisible by 7. The code initializes three variables: i, n, and a. i is used as a counter in the for loop, n is set to 7 (the divisor we're checking for), and a is set to 100 (the maximum number we're checking). The for loop then starts from 1 and runs until i is greater than a. WebSuppose we have n which is divisible by 7 and we want to prove it, write it in the form n = 10 k + j so j. Notice that j is the last digit in the decimal expansion. Now here's the trick, because 7 n we know 7 ( n − 21 j) so 7 10 ( k − 2 j). 10 and 7 are relatively prime so we get that 7 ( k − 2 j).
