Find the one which does not belong to that group ?a)16b)28c)36d)64e)4C...
The given options are 16, 28, 36, 64, and 4. We need to identify the option that does not belong to the group.
Factors of the Numbers
To determine the odd one out, let's find the factors of each number.
16:
Factors of 16 are 1, 2, 4, 8, and 16.
28:
Factors of 28 are 1, 2, 4, 7, 14, and 28.
36:
Factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36.
64:
Factors of 64 are 1, 2, 4, 8, 16, 32, and 64.
4:
Factors of 4 are 1, 2, and 4.
Odd One Out
By comparing the factors of each number, we can observe that all the numbers except 4 are perfect squares. The factors of 4 do not include any other perfect square, while the factors of the other numbers include at least one perfect square.
Therefore, the number 4 is the odd one out because it is not a perfect square like the other numbers.
Conclusion
Among the given options, the number 4 does not belong to the group because it is not a perfect square, unlike the other numbers.
