The greatest common factor of 90 , 30 , 45 = 15
Because 45 is not a factor of 60.
The GCF is 3.
The GCF is 5.
The Greatest Common Factor (GCF) is: 5
The GCF is: 30
1,3,5,15
Because 45 is not a factor of 60.
The Greatest Common Factor of 60, 45, and 30 is 15.
The Greatest Common Factor (GCF) of 45 and 30 is 15. The Least Common Multiple (LCM) of 45 and 30 is 90.
The GCF is 15.
Since 15 is a factor of 45, it is automatically the GCF.
