Given the numbers:
[tex]615\text{ and 570}[/tex]Let's find their greatest common factor:
Step 1: Let's determine the factors of the numbers.
a.) 570
The factors of 570 are: 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570
b.) 615
The factors of 615 are: 1, 3, 5, 15, 41, 123, 205, 615
Their common factors are: 1, 3, 5, 15
But the greatest among all factors is 15.
Therefore, their greatest common factor (GCF) is 15.
