Use divisibility tests to decide whether the first number is divisible by the second. 6,955,200; 7[Note that a divisibility test for 7 is as follows: Double the last digit of the number and subtract this value from the original number with the last digit omitted. Repeat this process as many times as necessary until the number obtained can easily be divided by 7. If the final number obtained is divisible by 7, then so is the original number. If the final number obtained is not divisible by 7, then neither is the original number.]
