You asked:

Find all common factors of 4040 and 5050.

MathBot Answer:

All common factors of a set of numbers will be factors of the greatest common factor, or GCF, of that set. Start by finding the GCF.

 

gcf(40,50)=10\text{gcf}(40, 50) = 10

 

Then find the factors of that gcf. One way to do this is to use a factor table. Attempt to divide the number by a series of possible factors, starting with 11. Place 11 in the left-hand column, and the quotient in the right-hand column. Increase the number in the left-hand column, skipping numbers that don't divide the greatest common factor, until a number in the left-hand column that is already in the right-hand column appears.

 

110
25
52

 

The common factors are: 1,2,5,101,2,5,10
