1,2,4,8 & 16.
The common factors are: 1, 2, 4, 8, 16.
Factors of 80 = 1, 2, 4, 5, 8, 10, 16, 20, 40, 80.Prime factors = 2, 5.
The common factors of 55 and 80 are 1 and 5
Two of the factors of 80 are prime numbers: 2 and 5.
The factors for 80 are: 10, 8, 40, 2, 20, 4, 1, 80, 16 and 5.
Common factors of 72 and 80 are: 1, 2, 4, and 8.
Since 80 is a factor of 160, all of its factors are common.
Since 40 is a factor of 80, all of its factors are common.
We won't be able to find factors of 80 that are not factors of 80. The factors of 80 that aren't factors of 42 are 4, 5, 8, 10, 16, 20, 40 and 80.
4, 8, 10, 16, 20, 40, 80
1,2,4,8 & 16.
To find the common factors of 25 and 80, we first determine the factors of each number. The factors of 25 are 1, 5, and 25, while the factors of 80 are 1, 2, 4, 5, 8, 10, 16, 20, 40, and 80. The common factors shared by both numbers are 1 and 5. To find the sum of these common factors, we add them together: 1 + 5 = 6. Therefore, the sum of all the common factors of 25 and 80 is 6.
1 and 2
1, 2, 4, 5, 8, 10, 16, 20, 40, 80
Since 20 is a factor of 80, all of its factors are common.
All numbers have factors. Some numbers have some of the same factors as other numbers. Multiples of numbers have all of the factors of numbers that are factors of them, plus some of their own. 32 is a multiple of 16 and will have all of its factors. 64 is a multiple of both 32 and 16 and will have all of their factors.
