What is the Divisibility Rule of 693?

The divisibility rule for 693 is a method by which we can find out if a number is divisible by 693 or not without using the division method. Check whether 1386 is divisible by 693 using the divisibility rule.
 

Step 1: Break down 693 into its prime factors: 693 = 3 × 3 × 7 × 11.

Step 2: Check if the number is divisible by each of these factors.
 

To check divisibility by 3, ensure the sum of the digits is divisible by 3.

For 1386, 1 + 3 + 8 + 6 = 18, which is divisible by 3.
 

To check divisibility by 7, follow the specific rule for 7 (as described earlier).

For 1386, double the last digit (6): 6 × 2 = 12. Subtract from the remaining number: 138 - 12 = 126. Since 126 is divisible by 7, 1386 passes this test.
 

To check divisibility by 11, see if the difference between the sum of the digits in odd positions and the sum of the digits in even positions is a multiple of 11.

For 1386, (1 + 8) - (3 + 6) = 9 - 9 = 0, which is a multiple of 11.
 

Since 1386 is divisible by 3, 7, and 11, it is divisible by 693.divisibility rule of 693
