Is 87 divisible by 7?
No, 87 is not divisible by 7. To determine if a number is divisible by 7, you can use the rule that states a number is divisible by 7 if the difference between twice the digit in the ones place and the number formed by the other digits is either 0 or a multiple of 7. In this case, the number formed by the other digits is 8, and twice the digit in the ones place is 14. The difference between 14 and 8 is 6, which is not a multiple of 7, so 87 is not divisible by 7.

What is the divisibility test for 7?
You can determine if a number is divisible by 7 by using the following method: E.g. 161 - Double the last digit (2 x 1 = 2) Subtract 2 from the number formed by the the remaining digits in this case, 16 -2 = 14 If the result is divisible by 7 (14 /7 =2); then the original number is divisible by 7. 161 / 7 = 23

Is 14 divisible by 7 and 2?
well any number is divisible by any other number, but 14 is divisible by both 7 and 2 and you get a whole number. 14 divided by 7 = 2 and 14 divided by 2 = 7
13 is a prime number so is 14 a prime number?
No. A prime number (or a prime) is a natural number which has exactly two distinct natural number divisors: 1 and itself. 13 is only divisible by 1 and itself (13). 14 is also divisible by 2 and 7, therefor is not a prime number.
