Given numbers are 643, 621, 179, 707

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

Apply this formula for all numbers.

Step1:

LCM(643, 621) = 399303

GCD(643, 621) = ( 643 x 621 ) / 399303

= 643 / 621

= 643

Step2:

LCM(1, 179) = 179

GCD(1, 179) = ( 1 x 179 ) / 179

= 1 / 179

= 1

Step3:

LCM(1, 707) = 707

GCD(1, 707) = ( 1 x 707 ) / 707

= 1 / 707

= 1

So, Greatest Common Divisor of 643, 621, 179, 707 is 1
