Given numbers are 643, 403, 377, 679

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

Apply this formula for all numbers.

Step1:

LCM(643, 403) = 259129

GCD(643, 403) = ( 643 x 403 ) / 259129

= 643 / 403

= 643

Step2:

LCM(1, 377) = 377

GCD(1, 377) = ( 1 x 377 ) / 377

= 1 / 377

= 1

Step3:

LCM(1, 679) = 679

GCD(1, 679) = ( 1 x 679 ) / 679

= 1 / 679

= 1

So, Greatest Common Divisor of 643, 403, 377, 679 is 1
