Given numbers are 128, 252, 363, 521

The list of prime factors of all numbers are

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

Prime factors of 252 are 2 x 2 x 3 x 3 x 7

Prime factors of 363 are 3 x 11 x 11

Prime factors of 521 are 521

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

Given numbers are 128, 252, 363, 521

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

Apply this formula for all numbers.

Step1:

LCM(128, 252) = 8064

GCD(128, 252) = ( 128 x 252 ) / 8064

= 128 / 252

= 128

Step2:

LCM(4, 363) = 1452

GCD(4, 363) = ( 4 x 363 ) / 1452

= 4 / 363

= 4

Step3:

LCM(1, 521) = 521

GCD(1, 521) = ( 1 x 521 ) / 521

= 1 / 521

= 1

So, Greatest Common Divisor of 128, 252, 363, 521 is 1
