Divisible by 8
Divisible by 8 is discussed below:
A number is divisible by 8 if the numbers formed by the last three digits is divisible by 8.
I: Consider the following numbers which are divisible by 8, using the test of divisibility by 8:
1792, 1824, 2000, 2880, 3320.
(i) 1792
In 1792 the last three digits are 792, which is divisible by 8.
Hence, 1792 is divisible by 8.
(ii) 1824
In 1824 the last three digits are 824, which is divisible by 8.
Hence, 1824 is divisible by 8.
(iii) 2000
In 2000 the last three digits are 000, which is divisible by 8.
Hence, 2000 is divisible by 8.
(iv) 2880
In 2880 the last three digits are 880, which is divisible by 8.
Hence, 2880 is divisible by 8.
(v) 3320
In 3320 the last three digits are 320, which is divisible by 8.
Hence, 3320 is divisible by 8.
II: Consider the following numbers which are not divisible by 8, using the rules of divisibility by 8:
1423, 1988, 2018, 2807, 3732.
(i) 1423
In 1423 the last three digits are 423, which is not divisible by 8.
Hence, 1423 is also not divisible by 8.
(ii) 1988
In 1988 the last three digits are 988, which is not divisible by 8.
Hence, 1988 is also not divisible by 8.
(iii) 2018
In 2018 the last three digits are 018, which is not divisible by 8.
Hence, 2018 is also not divisible by 8.
(iv) 2807
In 2807 the last three digits are 807, which is not divisible by 8.
Hence, 2807 is also not divisible by 8.
(v) 3732
In 3732 the last three digits are 732, which is not divisible by 8.
Hence, 3732 is also not divisible by 8.
