gcf implies greatest common factor or divisor(gcd) while LCM mean least common multiple.given two integers a and b (a,b) will denote the positive gcf of the integers.Thus 2=(2,4 )=(-2,4)=(-2,-4)=(2,4).Also, for any integer a and b, we have that (a,-b)=(a,b)=(-a,b)=(-a,-b)=(b,a).
Similarly, any two non-zero integer a and b have a positive gcd(a,b), and also have a least positive common multiple(LCM). The LCM is denoted by [a,b] i.e a square bracket. note that for gcd, we use an ordinary bracket.
It is also worth to know the relationship between gcd and LCM.This is given by:
[a,c]=|ac|/( a,c) for any non-zero integers a and c. Take note that |ac| implies the absolute value of a*c.
Thanks.

lcm means least common multiple and gcf mean greatest common factor
The GCF is 1. That means the LCM is the two numbers multiplied together, or 210.
The GCF is 12. The LCM is 360.
The GCF is 4.
The GCF is 68, the LCM is 68
GCF is 2.LCM is 42.The GCF is 2.
The LCM is 11592. The GCF is 2.
The GCF and LCM of 24 and 42 are 6 and 168 respectively.
The GCF refers to whole numbers, not decimals.
The GCF is: 16The LCM is: 640The LCM is: 640
Greatest Common Factor (GCF) for 72 168 is 24.Least Common Multiple (LCM) for 72 168 is 504.
The GCF is 15. The LCM is 450.
