What is the greatest common factor of 42a5b3, 35a3b4, and 42ab4?

.

Step-by-step explanation:

We have been given three expressions. We are asked to find the greatest common factor of our expressions.

, ,

The greatest common factor is the factor that divides two or more numbers.

Factors of coefficient:

42: 1, 2, 3, 6,7, 14, 21, 42

35: 1, 5, 7, 35

The greatest common factor of coefficient is 7.

The greatest common factor of is .

Upon combining all these factors, we will get .

Therefore, the greatest common factor of , and is .

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
