The GCF is 7b.
Oh, dude, the greatest common factor in 21ab and 14b is 7b. You just gotta look at the numbers and variables and find the biggest one that they both share. It's like finding the coolest party that both 21ab and 14b want to go to.
You can take 7b out of both of those, leaving 3a and 2

The greatest common factor is 7a.21ab+35a=7a(3b+5)GCF(21ab, 35a) = 7a. How? Factor out each term to get:21ab = 3 x 7 x a x b35a = 5 x 7 x aThe factors that occur both in 21ab and 35a are 7 and a. Therefore, the GCF is 7a.
The prime factors of 21 are 3 and 7.The prime factors of 14 are 2 and 7.The greatest common factor of 21 and 14 is 7.21ab and 14b also have another factor in common - b. So, the greatest common factor of 21ab and 14b would appear to be 7b . However, it is possible that a and 14 share a common factor of 2, in which case the greatest common factor of 21ab and 14b would be 14b.In summary, if a is an even number (i.e. having a factor of 2), the greatest common factor is 14b.If a is not an even number, the greatest common factor is 7b.gcf(21ab, 14b) = 7b.
7b.

The LCM is 42a2b3.
You need at least two terms to find a GCF.
You can take 7b out of both of those, leaving 3a and 2
