Given numbers are 328, 787, 621, 628

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

Apply this formula for all numbers.

Step1:

LCM(328, 787) = 258136

GCD(328, 787) = ( 328 x 787 ) / 258136

= 328 / 787

= 328

Step2:

LCM(1, 621) = 621

GCD(1, 621) = ( 1 x 621 ) / 621

= 1 / 621

= 1

Step3:

LCM(1, 628) = 628

GCD(1, 628) = ( 1 x 628 ) / 628

= 1 / 628

= 1

So, Greatest Common Divisor of 328, 787, 621, 628 is 1
