These flashcards are great!
I noticed a small typo in the Quants section Page 41 (according to adobe reader).
The text of slide is below -->
**********
Q: Highest Common Factor (HCF), Lowest Common
Multiple (LCM) – Prime Factorization
(x^r)(y^r) = (xy)^r
(3^3)(4^3) = 12^3 = 1728
Remember: purchase price is not the same as
market value.
Odd numbers have only odd factors.
1. Start by writing each number as product of its prime factors.
2. Write so that each new prime factor begins in same place.
3. Highest Common Factor is found by multiplying all factors
appearing on BOTH lists.
60 = 2 x 2 x 3 x 5
72 = 2 x 2 x 2 x 3 x 3
HCF = 2 x 2 x 3 = 12
4. Lowest common multiple found by multiplying all factors in
EITHER list.
60 = 2 x 2 x 3 x 5
72 = 2 x 2 x 2 x 3 x 3
HCF = 2 x 2 x 2 x 3 x 3 x 5 = 360
**********
I believe the '
HCF' towards the bottom of the slide should be '
LCM'.
Keep up the great work
