Given numbers are 838, 645, 285, 692

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

Apply this formula for all numbers.

Step1:

LCM(838, 645) = 540510

GCD(838, 645) = ( 838 x 645 ) / 540510

= 838 / 645

= 838

Step2:

LCM(1, 285) = 285

GCD(1, 285) = ( 1 x 285 ) / 285

= 1 / 285

= 1

Step3:

LCM(1, 692) = 692

GCD(1, 692) = ( 1 x 692 ) / 692

= 1 / 692

= 1

So, Greatest Common Divisor of 838, 645, 285, 692 is 1
