The divisibility rule is a way to find out whether a number is divisible by another number without using the division method. In real life, we can use the divisibility rule for quick math, dividing things evenly, and sorting things. In this topic, we will learn about the divisibility rule of 251.
The divisibility rule for 251 is a method by which we can find out if a number is divisible by 251 or not without using the division method. Check whether 75351 is divisible by 251 with the divisibility rule.
Step 1: Multiply the last digit of the number by a certain factor. For 251, this factor is 26. In 75351, 1 is the last digit, multiply it by 26. 1 × 26 = 26.
Step 2: Subtract the result from Step 1 from the remaining values but do not include the last digit. i.e., 7535 - 26 = 7509.
Step 3: Repeat the process with the new number (7509) if necessary. Since 7509 is still a large number, repeat the process. The last digit is 9, 9 × 26 = 234. Subtract from the remaining number, 750 - 234 = 516.
Step 4: Since 516 is still large, continue the process. The last digit is 6, 6 × 26 = 156. Subtract from 51, 51 - 156 = -105.
Step 5: Since the result is negative, take the absolute value, 105. Repeat the process again with 105. The last digit is 5, 5 × 26 = 130. Subtract from 10, 10 - 130 = -120.
Step 6: Take the absolute value again, which is 120. Since 120 is not a multiple of 251, the original number is not divisible by 251.
