Use divisibility tests to decide whether the first number is divisible by the second. 139,243,105; 11[Note that a divisibility test for 11 is as follows: Starting at the left of the number, add together every other digit. Add together the remaining digits. Subtract the smaller of the two sums from the larger. If the final number obtained is divisible by 11, then so is the original number. If the final number obtained is not divisible by 11, then neither is the original number.]
