4 x 27 x 3125 = 2² x 3³ x 5⁵
8 x y x 25 x 7 = 2³ x y x 5² x 7¹
16 x 81 x 5 x 11 x 49 = 2⁴ x 3⁴ x 5¹ x 11¹ x 7²
If y = 9, HCF = 2² x 3² x 5¹ = 180
If y = 27, HCF = 2² x 3³ x 5¹ = 540
8 x y x 25 x 7 = 2³ x y x 5² x 7¹
16 x 81 x 5 x 11 x 49 = 2⁴ x 3⁴ x 5¹ x 11¹ x 7²
If y = 9, HCF = 2² x 3² x 5¹ = 180
If y = 27, HCF = 2² x 3³ x 5¹ = 540
