You need at least two numbers to find something in common between them.
Factors of 20 are 1, 2, 4, 5, 10 and 20. And their sum is 1 + 2 + 4 + 5 + 10 + 20 = 32.
1 + 2 + 4 = 7
Since 20 is a factor of 40, all of its factors are common.
The common factors of 22 and 20 are: 1 and 2.
The answer to the question is: "All of the common factors of 10, 25, and 20 are 1 and 5 ."
The common factors are: 1, 2, 4
20: 1,2,4,5,10,2050: 1,2,5,10,25,50Common Factors: 1,2,5,10
1 and 2 are factors common to 6 and 20
Common factors of 18 and 20 are: 1 and 2.
10 and -5 are factors of -20.
Factors for 20 are: 1, 2, 4, 5, 10, 20 Prime Factors: 2, 5 sum of prime factors = 2 + 5 = 7
Since 20 is a factor of 100, all of its factors are common.
