Question

What is the least value of K so that the number 6735K1 is divisible by 9?

Answer 1

Answer:

the smallest number is 5.

Step-by-step explanation:

To check the divisibility of 9, all the digits must be added and check if the result is multiple of 9.

6 + 7 + 3 + 5 + K + 1 = 22 + k

Now, the result must be 27 because more than 22 is 27 which is a multiple of 9.

22 + k = 27

k = 27 - 22

k = 5

the smallest number is 5.

What is divisibility?

Divisibility rules in math are a set of specific rules that apply to a number to check whether the given number is divisible by a particular number or not. Some known divisibility tests are for numbers 2 to 20. It helps us to find the factors and multiples of numbers without performing long division.
