Question

examine whether 591 is a multiple of 7​

Answer 1

Answer:

no

Step-by-step explanation:

as it is not satisfying the divisibility rule

Answer 2

Given: A number 591

To find: If the number is a multiple of 7

Solution: The divisibility rule of 7 states that for a number to be divisible by 7, the last digit of the given number should be multiplied by 2 and then subtracted with the rest of the number leaving the last digit. If the difference is 0 or a multiple of 7, then it is divisible by 7.

As such, multiplying the last digit of 591 with 2 we get,

1 × 2 = 2.

Now subtracting this from the rest of the number leaving the last digit ⇒

59 - 2 = 57.

This difference, that is, 57, is not 0. Neither is it a multiple of 7.

Hence, 591 is not a multiple of 7.
