91 has more than 2 factors. It is composite.
144 has 15 factors: 1 2 3 4 6 8 9 12 16 18 24 36 48 72 144.
It has more than three factors which are: 1 2 3 4 6 9 12 18 and 36
The factors of 18 are: 1 2 3 6 9 18 The prime factors are: 2 x 3 x 3
The factors of 18 are 1, 2, 3, 6, 9, and 18. The prime factors are 2, 3 and 3.
A number which has more than two factors is called composite number. Factors of 18 are 1, 2, 3, 6, 9 and 18. As it can be seen 18 has more than two factors so, 18 is composite.
factorise it and get your answer- 30=2*3*5 18=2*3*3 same number of factors
2 x 9 = 18, so 18 has more factors than 1 and itself. It cannot be prime because a prime number has two factors: 1 and itself.
Any number with more than 2 factors is composite.12 has six factors, so it's composite.18 also has six factors, so it's composite too.(Only 4 of the factors of 8 are the same as 4 of the factors of 12)
18 = 2*3*3 So composite factors of 18 are: 2*3 = 6 3*3 = 9 and 2*3*3 = 18 These are all the factors of 18 other than 1 and its prime factors (2 and 3)
91 has more than 2 factors. It is composite.
ways to multiply 90 more than 2 factors
No a prime number has only 2 factors which are itself and one but a composite number has more than 2 factors
Factors of 2 : 1, 2 Factors of 18 : 1, 2, 3, 6, 9, 18
An Abundant Number is one that the factors (other than itself) add up to more than the number. 18 factors into [2 3 3] so the factor list is {1 2 3 6 9 18} and the sum of the rest is 21. Since 21 is greater than 18, it is an abundant number.Yes 18 is an abundant number because if you add all of it's factors (1,2,3,6,9,) together the sum is 21.Definition of Abundant- a number that is less the sum of it's factors or integers
A whole number with more than 2 factors is a composite number.
12 (factors: 1, 2, 3, 4, 6, 12) and 18 (factors: 1, 2, 3, 6, 9, 18)
