What are factors of 8 and?
The factors of 8 are 1, 2, 4, and 8. 1 is a universal factor because it is a factor of all numbers. Factors are quite often given as pairs of numbers which when multiplied together give the original number. The factors of 8 in pairs are (2, 4) and (1, 8).
Is 8 a composite number Why?
All the even numbers which are not prime are even composite numbers. For example, 4, 6, 8, 10, 12, 14, 16, are even composite numbers. Consider the numbers 1, 2, 3, 4, 9, 10, 11, 12 and 15 again. Here 4, 10, and 12 are the even composites because they have even divisors and satisfy the composite condition.
Is eight a composite number?
