Given numbers are 621, 723, 435, 178

The list of prime factors of all numbers are

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

Prime factors of 723 are 3 x 241

Prime factors of 435 are 3 x 5 x 29

Prime factors of 178 are 2 x 89

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

Given numbers are 621, 723, 435, 178

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

Apply this formula for all numbers.

Step1:

LCM(621, 723) = 149661

GCD(621, 723) = ( 621 x 723 ) / 149661

= 621 / 723

= 621

Step2:

LCM(3, 435) = 435

GCD(3, 435) = ( 3 x 435 ) / 435

= 3 / 435

= 3

Step3:

LCM(3, 178) = 534

GCD(3, 178) = ( 3 x 178 ) / 534

= 3 / 178

= 3

So, Greatest Common Divisor of 621, 723, 435, 178 is 1
