Given numbers are 403, 364, 642, 395

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

Apply this formula for all numbers.

Step1:

LCM(403, 364) = 11284

GCD(403, 364) = ( 403 x 364 ) / 11284

= 403 / 364

= 403

Step2:

LCM(13, 642) = 8346

GCD(13, 642) = ( 13 x 642 ) / 8346

= 13 / 642

= 13

Step3:

LCM(1, 395) = 395

GCD(1, 395) = ( 1 x 395 ) / 395

= 1 / 395

= 1

So, Greatest Common Divisor of 403, 364, 642, 395 is 1
