The list of prime factors of all numbers are

Prime factors of 561 are 3 x 11 x 17

Prime factors of 245 are 5 x 7 x 7

Prime factors of 508 are 2 x 2 x 127

Prime factors of 528 are 2 x 2 x 2 x 2 x 3 x 11

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

Given numbers are 561, 245, 508, 528

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

Apply this formula for all numbers.

Step1:

LCM(561, 245) = 137445

GCD(561, 245) = ( 561 x 245 ) / 137445

= 561 / 245

= 561

Step2:

LCM(1, 508) = 508

GCD(1, 508) = ( 1 x 508 ) / 508

= 1 / 508

= 1

Step3:

LCM(1, 528) = 528

GCD(1, 528) = ( 1 x 528 ) / 528

= 1 / 528

= 1

So, Greatest Common Divisor of 561, 245, 508, 528 is 1
