Examples on factors on different types of questions on factors are discussed here step-by-step.
1. Find all the factors of 42.
Solution:
According to properties of factors, 1 and 42 are the factors of 42.
Now we find the numbers which completely divide 42.
By dividing the numbers we find the factors of 42.
Thus, 1, 2, 3, 7 are complete dividers.
2 x 3 = 6; 3 x 7 = 21; 2 x 7 = 14; are also divisors.
Hence, 1, 2, 3, 6, 7, 14, 21 and 42 are the factors of 42.
2. Check if:
(i) 9 is a factor of 74,
(ii) 7 is a factor of 84.
Solution:
(i)
74 is not divisible by 9.
So, 9 is not a factor of 74.
(ii)
84 is divisible by 7.
So, 7 is a factor of 84.
