| Finding the Least Common Multiple 
			(LCM): 
				
					
						| LCM is found under  MATH → NUM, arrow down to #8:  lcm( 
 | From the home screen, choose 
						lcm(  followed by 
					  two numbers separated by a comma. | 
						 |  
						| NOTE: 
					    lcm( accepts 
						non-negative integers only and works with only two 
						entries at a time.
 |  
						| Example: Find the LCM for 10, 15, and 45.
 
 | Since LCM can only accept two entries 
						at a time, find the LCM of the first two values, and 
						then find the LCM of your answer and the third value. | 
						 |    Finding the 
			Greatest  Common Factor (GCF): 
				
					
						|  NOTE:  
						The calculator refers to the GCF as the 
					  GCD, greatest common divisor. |  
						| GCD is found under  MATH → NUM, arrow down to #9:  gcd( | From the home screen, choose 
						gcd(  followed by 
					  two numbers separated by a comma. | 
						 |  
						| NOTE: 
					    gcd(						  accepts non-negative integers only and works with 
						only two entries at a time.
 |  
						| Example: Find the GCF (or GCD) for 12, 24, and 32.
 
 | Since GCD can only accept two entries 
						at a time, find the GCD of the first two values, and 
						then find the GCD of your answer and the third value. |
