Given numbers are 553, 516, 645, 261

The list of prime factors of all numbers are

Prime factors of 553 are 7 x 79

Prime factors of 516 are 2 x 2 x 3 x 43

Prime factors of 645 are 3 x 5 x 43

Prime factors of 261 are 3 x 3 x 29

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

Given numbers are 553, 516, 645, 261

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

Apply this formula for all numbers.

Step1:

LCM(553, 516) = 285348

GCD(553, 516) = ( 553 x 516 ) / 285348

= 553 / 516

= 553

Step2:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

Step3:

LCM(1, 261) = 261

GCD(1, 261) = ( 1 x 261 ) / 261

= 1 / 261

= 1

So, Greatest Common Divisor of 553, 516, 645, 261 is 1
