Given numbers are 642, 824, 795, 381

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

Apply this formula for all numbers.

Step1:

LCM(642, 824) = 264504

GCD(642, 824) = ( 642 x 824 ) / 264504

= 642 / 824

= 642

Step2:

LCM(2, 795) = 1590

GCD(2, 795) = ( 2 x 795 ) / 1590

= 2 / 795

= 2

Step3:

LCM(1, 381) = 381

GCD(1, 381) = ( 1 x 381 ) / 381

= 1 / 381

= 1

So, Greatest Common Divisor of 642, 824, 795, 381 is 1
