The Divisibility Rule of 618

The divisibility rule for 618 is a method by which we can find out if a number is divisible by 618 or not without using the division method. Check whether 1236 is divisible by 618 with the divisibility rule.

Step 1: Check if the number is divisible by 2, 3, and 103 because 618 = 2 × 3 × 103.

Step 2: For divisibility by 2, the number must be even. Since 1236 ends in 6, it is even.

Step 3: For divisibility by 3, sum the digits: 1 + 2 + 3 + 6 = 12. Since 12 is divisible by 3, 1236 is divisible by 3.

Step 4: For divisibility by 103, perform actual division or check with known multiples of 103. Since 1236 divided by 103 equals 12, it is divisible.

Since 1236 is divisible by 2, 3, and 103, it is divisible by 618.
