20 is a factor of 40, among many other numbers.
The factor numbers are: 4 x 5 2 x 10 1 x 20
Two numbers whose greatest common factor (GCF) is 20 are any pair of numbers that are multiples of 20. For example, 20 and 40 have a GCF of 20 because 20 is a factor of both numbers. Another pair could be 60 and 80, as 20 is also a factor of both of these numbers.
1,2,4,5,10,20
The factor pairs of 20 are pairs of numbers that can be multiplied together to give 20. The factor pairs of 20 are (1, 20), (2, 10), and (4, 5). These pairs represent all the possible combinations of numbers that can be multiplied to equal 20.
It would be 20. After dividing both numbers by 20, you get 1 and 6. And these two numbers cannot be divided by any other numbers except by 1.
A common factor is a factor both numbers can be evenly divided by.In this case it is 20.20/20 = 180/20 = 4
20 and 30 are two numbers that have the greatest common factor of 10.
5 is a prime factor of both numbers.
Common factor
A factor is the two numbers you multiply for example: 20x20=400 Both 20 and 20 are factors. The 400 is a product.
There can be only one greatest common factor for any set of numbers. GCF(40, 20) = 20.
