Given numbers are 642, 122, 411, 323

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

Apply this formula for all numbers.

Step1:

LCM(642, 122) = 39162

GCD(642, 122) = ( 642 x 122 ) / 39162

= 642 / 122

= 642

Step2:

LCM(2, 411) = 822

GCD(2, 411) = ( 2 x 411 ) / 822

= 2 / 411

= 2

Step3:

LCM(1, 323) = 323

GCD(1, 323) = ( 1 x 323 ) / 323

= 1 / 323

= 1

So, Greatest Common Divisor of 642, 122, 411, 323 is 1
