Given numbers are 486, 495, 198, 128

The list of prime factors of all numbers are

Prime factors of 486 are 2 x 3 x 3 x 3 x 3 x 3

Prime factors of 495 are 3 x 3 x 5 x 11

Prime factors of 198 are 2 x 3 x 3 x 11

Prime factors of 128 are 2 x 2 x 2 x 2 x 2 x 2 x 2

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 486, 495, 198, 128

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(486, 495) = 26730

GCD(486, 495) = ( 486 x 495 ) / 26730

= 486 / 495

= 486

Step2:

LCM(9, 198) = 198

GCD(9, 198) = ( 9 x 198 ) / 198

= 9 / 198

= 9

Step3:

LCM(9, 128) = 1152

GCD(9, 128) = ( 9 x 128 ) / 1152

= 9 / 128

= 9

So, Greatest Common Divisor of 486, 495, 198, 128 is 1
