Explanation
Factors of 24=1,2,3,4,6,8,12,24Factors of 36=1,2,3,4,6,9,12,18,36
Factors of 92=1,2,4,23,46,92
Common factors are =1,2,4∴ HCF =4
Step -1: Solve with example
As we know Factors are all the numbers that divide a number completely,
i.e., without leaving any remainder, are called factors of that number.
Multiples are those numbers which on multiplication give the desired number.
All these multiples individually can be named as a factor of the given number.
Step -2: Find factors
To find the factors of any given number,
we express each number as a product of prime numbers since they do not leave any remainder.
For example, consider some numbers such as 1, 8, 21, 29.The factor of 1 is 1.
The factors of 8 are 1, 2, 4 and 8.
The factors of 21 are 1, 3, 7 and 21
The factors of 29 are 1 and 29.
From the above data, we observe that -
1 is the greatest factor of itself and the smallest factor of any other number.
Hence, the correct answer is option A, C, D.
