1, 5, 13, 65
The list of factors of 50.
The product of all the common prime factors is the GCF. The product of all common factors would vary according to the list.
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.
The list of factors of 50.
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.
The factors of 65 are: 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.
-- List all factors of the first number. -- List all factors of the second number. -- If there are more than two numbers, list all factors of each one. -- Find the set of factors that are on every list. -- Find the greatest factor in the set.
