find all factors of 61
The factors of 20 are: 1, 2, 4, 5, 10, 20
The prime factors of 20 are 2x2x5.
NO because 5 is a factor of 20 and its odd
Yes 20 is an ABUNDANT number because 1+2+4+5+10=22 and that is more than 20. PS how to find and ABUNDANT number is to add up all its factors. :)
1 and 5 are the factors of 20 which are odd.
The factors of 20 are 1,2,4,5,10 and 20. For them to be common, they need to be compared to another set of factors. There cannot be a common factor of just one number. To be common there need to be at least two numbers. If you find all the factors of two or more numbers, and you find some factors are the same ("common"), then the largest of those common factors is the Greatest Common Factor.The factorsof 20 are 1, 2, 4, 5, 10, 20. For them to be common, they need to be compared to another set of factors.
It's not, because all the factors of 20 aren't prime.

No. 1 and 5 are the factors of 20 which aren't even.
You need at least two numbers to find something in common between them.
20: 1,2,4,5,10,2050: 1,2,5,10,25,50Common Factors: 1,2,5,10
Because there are only six factors... 1,2,4,5,10 & 20
The factors of 20 are: 1, 2, 4, 5, 10, 20
Factors for 20 are: 1, 2, 4, 5, 10, 20 Prime Factors: 2, 5 sum of prime factors = 2 + 5 = 7
1). List all of the factors of 16. 2). List all of the factors of 20. 3). List all of the factors of 28. 4). Make a short list, comprised of any numbers that are on all three lists. These are the common factors of 16, 20, and 28. 5). Find the greatest number on the short list. That's the greatest common factor of 16, 20, and 28. If it is not 4, then an error has crept into your work, and you are doomed to return to Step-1 and eternally repeat the process until you get 4 .
The factors of 20 are: 1, 2, 4, 5, 10, 20The factors of 25 are: 1, 5, 25
