Given numbers are 408, 321, 128, 925

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

Apply this formula for all numbers.

Step1:

LCM(408, 321) = 43656

GCD(408, 321) = ( 408 x 321 ) / 43656

= 408 / 321

= 408

Step2:

LCM(3, 128) = 384

GCD(3, 128) = ( 3 x 128 ) / 384

= 3 / 128

= 3

Step3:

LCM(1, 925) = 925

GCD(1, 925) = ( 1 x 925 ) / 925

= 1 / 925

= 1

So, Greatest Common Divisor of 408, 321, 128, 925 is 1
