Divisibility of 29
Dear Student,
To find the divisibility of any number by 29, multiply the last digit of that number by 3 and add the product to the remaining number.
If the result i.e. the number obtained on multiplying the last digit by 3 and then adding to the remaining number, is divisible by 29, then, the number (number in question) is also divisible by 29.
Note: Please continue the process of multiplying the last number by 3 and adding it to the remaining number, till you get a small number like 29, so that dividing the result by 29 is an easy calculation.
For eg: take a number 348
Now, multiply its last digit i.e. 8 with 3
8*3=24
Add 24 to the remaining number i.e. 34
24+ 34= 58
Again repeating the same process.... multiply 3 to 8, then add it to remaining umber i.e. 5
So, 3*8+5= 29
Now, since 29 is divisible by 29 ( 29/29=1), 348 is also divisible by 29
