Q: What is a number less than 100 and has factor pairs?

Write your answer...

80 has 5 factor pairs.

12 and 18 have three factor pairs.

12 and 18 have three factor pairs.

The number 18.

12 and 18

12, 16, 18

24 does.

18 = 1x18, 18 = 2x9, and 18 = 3x6

Yes.

what is the number that has three digits less than 140 has7 factor the sum of the digits of the number is less than 9

Any factor of the number less than the number itself.

the number is 18

Single numbers don't have LCMs, much less pairs of them. Pairs of LCMs don't exist because only one number can be least. Other than that...The factor pairs of 36 are (36,1)(18,2)(12,3)(9,4)(6,6)

No single integer satisfies both requests. 80 is the only integer with exactly 5 factor pairs in that range, but it has two prime factors. 64 and 81 have one prime factor but 4 and 3 factor pairs respectively.

It's less than the first number.

No. The Maximum Factor for any number that is less than itself can be only 50% of its value.

No. In order for something to be a factor of a number, it has to be less than or equal to the number.

1 has only one factor.

1 has one factor.

112

2 and 7 are prime numbers less than 10 that are factors of 42 and 70.

Factor pairs of a number always come in the format of one factor larger than the square root of the number and one factor smaller than the square root of the number. In the case of square numbers, the square root is also a "factor pair." 9,801 happens to be the square of 99. So, once we find the factors of 99, we can divide them into 9,801 to find their pairs as factors of 9,801. The prime factorization of 99 is 3^2*11 So, our factor pairs of 9,801 are as follows: 1*9,801 3*3,267 9*1,089 11*891 33*297 99*99
