1, 5, 13, 65
The product of all the common prime factors is the GCF. The product of all common factors would vary according to the list.
To find the Greatest Common Factor (GCF) of 45 and 65, we first need to list the factors of each number. The factors of 45 are 1, 3, 5, 9, 15, and 45, while the factors of 65 are 1, 5, 13, and 65. The largest number that appears in both lists is 5, so the GCF of 45 and 65 is 5.
The factors of 55 are: 1, 5, 11, 55 The factors of 65 are: 1, 5, 13, 65
45 has 6 factors: 1,3,5,9,15,45
It is: 13
1, 5, 13, 65
1, 5, 13, 65.
1, 5, 13, 65
1 + 5 + 13 + 65 = 84
All non-zero numbers have factors. These can be written down in a list. That would be known as a list of factors.
65
5 and 13
They are 5 and 13
The first step to find the gcf of 85 and 145 is to list the factors of each number. The factors of 85 are 1, 5, 17 and 85. The factors of 145 are 1, 5, 29 and 145. So, the Greatest Common Factor for these numbers is 5 because it divides all them without a remainder.
That's an infinite list.
