Question

Find the H.C.F. of the following monomials (i)2a⁵and 12a² (ii)9x³y and 18x²y³ (iii)a²b³ and a³b² (iv)15a³,-45a²,150a (v)2x³y²,10x²y³,14xy (vi)x³y²,-8y²​

Answer 1

15a

2

−45a

2

=15a

2

(1−3)

=−30a

2

=−2×3×5×a×a

2

150a=2×3×5×5×a

H.C.F=30a

Answer 2

(i)2a⁵and 12a²

2a⁵

=2×a×a×a×a×a

12a²

=2×6×a×a

H.C.F=2×a×a

=2a²
