Given numbers are 621, 742, 552, 231

The list of prime factors of all numbers are

Prime factors of 621 are 3 x 3 x 3 x 23

Prime factors of 742 are 2 x 7 x 53

Prime factors of 552 are 2 x 2 x 2 x 3 x 23

Prime factors of 231 are 3 x 7 x 11

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

Given numbers are 621, 742, 552, 231

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

Apply this formula for all numbers.

Step1:

LCM(621, 742) = 460782

GCD(621, 742) = ( 621 x 742 ) / 460782

= 621 / 742

= 621

Step2:

LCM(1, 552) = 552

GCD(1, 552) = ( 1 x 552 ) / 552

= 1 / 552

= 1

Step3:

LCM(1, 231) = 231

GCD(1, 231) = ( 1 x 231 ) / 231

= 1 / 231

= 1

So, Greatest Common Divisor of 621, 742, 552, 231 is 1
