Pairs of numbers whose sum is -14 and that are factors of -189 include -7 and -7, and -21 and 7.
The factors of 42 are:1, 2, 3, 6, 7, 14, 21, 42The factors of 189 are:1, 3, 7, 9, 21, 27, 63, 189The factors of 441 are:1, 3, 7, 9, 21, 49, 63, 147, 441The common factors are:1, 3, 7, 21The Greatest Common Factor:GCF = 21
Well, honey, the Greatest Common Factor (GCF) of 189 and 20 is 1. Those two numbers don't have any common factors other than 1. So, there you have it, the sassy truth!
Since 189 is a multiple of both 9 and 27, it is automatically the LCM.
All numbers that have exactly two factors are prime numbers whereas composite numbers have more than two factors.
When the "factors" of a number are listed, the list is usually restricted to positive factors. Then there would be no answer to the question, because no group of positive numbers can add up to make zero.
3 x 63 = 189 3 + 63 = 66

You need at least two numbers to find something in common.
what two factors of -21 add up to -6
You need at least two numbers to find a GCF.
The answer is 210. Simply add the numbers together like you would for two plus two. To check your work, a calculator is the best option.
Prime numbers have only two factors which are themselves and one and they add up in the same way as composite numbers which have more than two factors
To find two numbers that multiply to give 378, you can consider its factors. One pair of numbers that works is 14 and 27, since 14 × 27 = 378. Another pair is 2 and 189, as 2 × 189 also equals 378.
The answer is 189. Simply add the numbers together arithmetically as you would for the problem two plus two. To check your work, a calculator is the best option.

There are many possible answers. The simplest of these is 1 and 189.
Answer: 1Definition: A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that the numbers have in common.Method:One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them.The factors of 25 are 1, 5, and 25.The factors of 189 are 1, 3, 7, 9, 21, 27, 63, and 189.The only common factor is 1. Therefore, the greatest common factor is 1, which means the numbers are relatively prime.
