you have to separate them and if both of them are in the 7 times table it is.
eg.3521 is it divisible by 7
35 + 21
the 35 is in the 7 timetable and so is the 21 so there both divisible by 7.
another eg.1442
14 + 21
14 is divisible by 7 and so is 21
yes it is .

What is the divisibility rule for 35?
If a number is divisible by 5 and 7, it's divisible by 35.
What is the divisibility rule for 42?
The divisibility rule for 42 isdivisibility by 2, ANDdivisibility by 3, ANDdivisibility by 7.Divisibility by 2 requires the number to be even. That means it must end in 0, 2, 4, 6 or 8.Divisibility by 3 requires that the digital root of the number is divisible by 3. That is, the sum of the digits is divisible by 3. If the first sum is large, you can calculate the digital root of the digital root (and again, if necessary) and check that for divisibility by 3.The divisibility rule for 7 is more difficult.Take the last digit (units).From the number formed by the remaining digit, subtract twice the last digit.If the answer is divisible by 7 (including zero or negative numbers), then the original number is divisible by 7.For large numbers, repeat the process to bring the number down to a manageable size.
What is divisibility rule of 7?
Double the last digit and subtract the last digit from the remaining digits.
What is the divisibility rule for 34?
There is no easy rule for divisibility by 34.
