Answer 1

Answer:

highest common factor for 6abc ,21ab^2and 12a^2b is 3ab

Step-by-step explanation:

6abc, 21 ab² and 12a²b

taking common a from each :

= a ( 6 bc, 21 b² , 12 ab )

taking common b from each :

= ab ( 6 c, 21 b, 12 a)

now,

taking common 3 from each :

= 3ab ( 2c , 7 b , 4 a)

Therefore,

highest common factor for 6abc ,21ab^2and 12a^2b is 3ab
