Given that a is a multiple of 456, find the greatest common divisor of 3a^3+a^2+4a+57 and a.

57

Step-by-step explanation:

Given: a is a multiple of 456

Let

Then, expression

Since 456 = 57 x 8

Then,

Taking 57 out as common

Now, the greatest common divisor of and is 57.

Hence, the greatest common divisor of 3a^3+a^2+4a+57 and a is 57.

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
