The factors of 18 are:
1, 2, 3, 6, 9, 18
The factors of 60 are:
1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60
The GCF is 3.
5 + 2 = 7
Since 60 is a factor of 360, it is automatically the GCF.
5 is a common factor of 25 and 60.
The greatest factor is 72 which is a factor of 72 (though not of 60).
The GCF of 18, 60, and 72 is 6.
The GCF of 18, 42 and 60 is 6.
The GCF is 6.
