Given numbers are 643, 591, 286, 622
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(643, 591) = 380013
GCD(643, 591) = ( 643 x 591 ) / 380013
= 643 / 591
= 643
Step2:
LCM(1, 286) = 286
GCD(1, 286) = ( 1 x 286 ) / 286
= 1 / 286
= 1
Step3:
LCM(1, 622) = 622
GCD(1, 622) = ( 1 x 622 ) / 622
= 1 / 622
= 1
So, Greatest Common Divisor of 643, 591, 286, 622 is 1
