Given numbers are 628, 218, 428, 195

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

Apply this formula for all numbers.

Step1:

LCM(628, 218) = 68452

GCD(628, 218) = ( 628 x 218 ) / 68452

= 628 / 218

= 628

Step2:

LCM(2, 428) = 428

GCD(2, 428) = ( 2 x 428 ) / 428

= 2 / 428

= 2

Step3:

LCM(2, 195) = 390

GCD(2, 195) = ( 2 x 195 ) / 390

= 2 / 195

= 2

So, Greatest Common Divisor of 628, 218, 428, 195 is 1
