Given numbers are 428, 424, 819, 325

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

Apply this formula for all numbers.

Step1:

LCM(428, 424) = 45368

GCD(428, 424) = ( 428 x 424 ) / 45368

= 428 / 424

= 428

Step2:

LCM(4, 819) = 3276

GCD(4, 819) = ( 4 x 819 ) / 3276

= 4 / 819

= 4

Step3:

LCM(1, 325) = 325

GCD(1, 325) = ( 1 x 325 ) / 325

= 1 / 325

= 1

So, Greatest Common Divisor of 428, 424, 819, 325 is 1
