Test the divisibility of each of the following numbers by 4:
(i) 134
(ii) 618
(iii) 3928
(iv) 50176
(v) 39392
(vi) 56794
(vii) 86102
(viii) 66666
(ix) 99918
(x) 77736
We know that if number formed by last two digits of a given number is divisible by 4, then entire given number is divisible by 4.
Here, number formed by last two digits is 34, which is not divisible by 4.
Hence, 134 is not divisible by 4.
(ii) 618
We know that if number formed by last two digits of a given number is divisible by 4, then entire given number is divisible by 4.
Here, number formed by last two digits is 18, which is not divisible by 4.
Hence, 618 is not divisible by 4.
(iii) 3928
We know that if number formed by last two digits of a given number is divisible by 4, then entire given number is divisible by 4.
Here, number formed by last two digits is 28, which is divisible by 4.
Hence, 3928 is divisible by 4.
(iv) 50176
We know that if number formed by last two digits of a given number is divisible by 4, then entire given number is divisible by 4.
Here, number formed by last two digits is 76, which is divisible by 4.
Hence, 50176 is divisible by 4.
(v) 39392
We know that if number formed by last two digits of a given number is divisible by 4, then entire given number is divisible by 4.
Here, number formed by last two digits is 92, which is divisible by 4.
Hence, 39392 is divisible by 4.
(vi) 56794
We know that if number formed by last two digits of a given number is divisible by 4, then entire given number is divisible by 4.
Here, number formed by last two digits is 94, which is not divisible by 4.
Hence, 56794 is not divisible by 4.
(vii) 86102
We know that if number formed by last two digits of a given number is divisible by 4, then entire given number is divisible by 4.
Here, number formed by last two digits is 02, which is not divisible by 4.
Hence, 86102 is not divisible by 4.
(viii) 66666
We know that if number formed by last two digits of a given number is divisible by 4, then entire given number is divisible by 4.
Here, number formed by last two digits is 66, which is not divisible by 4.
Hence, 66666 is not divisible by 4.
(ix) 99918
We know that if number formed by last two digits of a given number is divisible by 4, then entire given number is divisible by 4.
Here, number formed by last two digits is 18, which is not divisible by 4.
Hence, 99918 is not divisible by 4.
(x) 77736
We know that if number formed by last two digits of a given number is divisible by 4, then entire given number is divisible by 4.
Here, number formed by last two digits is 36, which is divisible by 4.
Hence, 77736 is divisible by 4.
