Answer 1

CORRECT QUESTIONS

The highest common factor in 15ab² , 20a²b , 12ab is

ANSWER

The answer is ab.

GIVEN

Algebraic expressions;

15ab² , 20a²b , 12ab

TO FIND

HCF

SOLUTION

We can simply solve the above problem as follows;

To find the HCF of the given expressions; we will find its factors.

15ab² = 3 × 5 × a × b × b

20a²b = 2 × 2 × 5 × a × a × b

12ab = 2 × 2 × 3 × a × b

HCF = a × b

Hence, The answer is ab.
