Six.
20 and 40 have 4 and 5 as common factors.
Composite numbers are those numbers which have more than 2 factors. Example: 4 has more than 2 factors (factors of 4 are- 1, 2 and 4) and hence is a composite number. Other examples are 6, 8, 9, 10, 12 etc.
Square numbers have odd numbers of factors. Examples: 4, 9, 16
The numbers are: 8 16 and 24
Factors don't have numbers. Numbers have factors. Numbers that have the factors 2, 4 and 8 are 8 and all of its multiples.
What two numbers have the factors 2 4 and 8
they are called numbers with 3 factors
4, with factors 1, 2 and 4
Six.
Numbers without factors are PRIME Numbers. Taking the first ten numbers. 1,2,3,4,5,6,7,8,9,10. The prime numbers are 2,3,5,7, they have no factors. 4,6,8,9,10. Are not prime numbers as they have factors. 4 has a factor of '2' 6 has factors of '2 & 3'. 8 has factors of' 2 & 4'. or' 2,2,2.' 9 has factors of '3,3', 10 has factors of '2 5.' '1' is unique
None because prime numbers have only two factors
(4) = 22
All numbers have factors. Some factors are prime numbers, some are composite numbers, one is neither. The factors of 12 are 1, 2, 3, 4, 6, 12 Since 4, 6 and 12 are composite numbers, they are the composite factors of 12.
All numbers have factors. Some numbers have some of the same factors as other numbers. These are common factors.
6, 8, 10, 14, 15,..., 501, 502, 505,... and countless other numbers have 4 factors.
1 and 2 are factors of both numbers.
