Given numbers are 643, 155, 192, 877

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

Apply this formula for all numbers.

Step1:

LCM(643, 155) = 99665

GCD(643, 155) = ( 643 x 155 ) / 99665

= 643 / 155

= 643

Step2:

LCM(1, 192) = 192

GCD(1, 192) = ( 1 x 192 ) / 192

= 1 / 192

= 1

Step3:

LCM(1, 877) = 877

GCD(1, 877) = ( 1 x 877 ) / 877

= 1 / 877

= 1

So, Greatest Common Divisor of 643, 155, 192, 877 is 1
