This worksheet is about finding the Highest Common Factor (HCF) of two algebraic expressions.
Find the HCF of 3p2qr3 and 6pq3r2
Take each term in turn.
HCF of 3 and 6 is 3.
HCF of p2 and p is p.
HCF of q and q3 is q.
HCF of r3 and r2 is r2.
So, required HCF is 3pqr2.
Find the HCF of 4y(y - 7)(7y + 4) and (y - 7)2(7y + 4)
The highest terms common to both are (y - 7) and (7y + 4).
So the HCF is (y - 7)(7y + 4)
