Given numbers are 621, 639, 452, 743

The list of prime factors of all numbers are

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

Prime factors of 639 are 3 x 3 x 71

Prime factors of 452 are 2 x 2 x 113

Prime factors of 743 are 743

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

Given numbers are 621, 639, 452, 743

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

Apply this formula for all numbers.

Step1:

LCM(621, 639) = 44091

GCD(621, 639) = ( 621 x 639 ) / 44091

= 621 / 639

= 621

Step2:

LCM(9, 452) = 4068

GCD(9, 452) = ( 9 x 452 ) / 4068

= 9 / 452

= 9

Step3:

LCM(1, 743) = 743

GCD(1, 743) = ( 1 x 743 ) / 743

= 1 / 743

= 1

So, Greatest Common Divisor of 621, 639, 452, 743 is 1
