Given numbers are 207, 642, 443, 446

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

Apply this formula for all numbers.

Step1:

LCM(207, 642) = 44298

GCD(207, 642) = ( 207 x 642 ) / 44298

= 207 / 642

= 207

Step2:

LCM(3, 443) = 1329

GCD(3, 443) = ( 3 x 443 ) / 1329

= 3 / 443

= 3

Step3:

LCM(1, 446) = 446

GCD(1, 446) = ( 1 x 446 ) / 446

= 1 / 446

= 1

So, Greatest Common Divisor of 207, 642, 443, 446 is 1
