Divisibility by 5, 6 | Concept Explained

Divisibility by 5

The Rule states: Any number ending with a "5" or "0" can always be divided by 5.
(This is so since multiples of "5" end with either a "0"or "5".)

This is one of the simplest rule in the Divisibility checking.

Concept: 5 times any integer always gives another number ending with a "0" or "5". Therefore by just simply looking at the last digit, we can determine whether the original number can be divided by 5.

Divisibility by 6

Rule: If any integer can be divided by 2 and also 3, then the number can be divided by 6.

Concept:
Since 2 and 3 are prime numbers that multiply to give a 6, these 2 numbers suffice to determine whether the original integer can be divided by 6.
