Given numbers are 628, 604, 397, 891

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

Apply this formula for all numbers.

Step1:

LCM(628, 604) = 94828

GCD(628, 604) = ( 628 x 604 ) / 94828

= 628 / 604

= 628

Step2:

LCM(4, 397) = 1588

GCD(4, 397) = ( 4 x 397 ) / 1588

= 4 / 397

= 4

Step3:

LCM(1, 891) = 891

GCD(1, 891) = ( 1 x 891 ) / 891

= 1 / 891

= 1

So, Greatest Common Divisor of 628, 604, 397, 891 is 1
