Given numbers are 628, 532, 788, 455

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

Apply this formula for all numbers.

Step1:

LCM(628, 532) = 83524

GCD(628, 532) = ( 628 x 532 ) / 83524

= 628 / 532

= 628

Step2:

LCM(4, 788) = 788

GCD(4, 788) = ( 4 x 788 ) / 788

= 4 / 788

= 4

Step3:

LCM(4, 455) = 1820

GCD(4, 455) = ( 4 x 455 ) / 1820

= 4 / 455

= 4

So, Greatest Common Divisor of 628, 532, 788, 455 is 1
