Using divisibility tests determine 297144 is divisible by 6 ​

Answer 1

Divisibility Rule for 6.

If the number is divisible by 2 and 3 it is also divisible by 6. So let's test the divisibility of 297144 with the 2 and 3.

Divisibility Rule for 2 ⇒ If the last digit of the number ends with 0, 2, 4, 6 or 8 they are known to be divisible by 2.

So, 297144 is divisible by 2 because the last digit is 4 and it is divisible by 2.

Divisibility Rule for 3 ⇒ If the sum of all numbers is equal to a multiple of 3 it is known to be divisible by 3.

So, 297144 ⇒ 2+9+7+1+4+4 = 27. 27 is a multiple of 3 so it is divisible by 3.

∴ 297144 is divisible by 6.
