Given numbers are 643, 524, 629, 605

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

Apply this formula for all numbers.

Step1:

LCM(643, 524) = 336932

GCD(643, 524) = ( 643 x 524 ) / 336932

= 643 / 524

= 643

Step2:

LCM(1, 629) = 629

GCD(1, 629) = ( 1 x 629 ) / 629

= 1 / 629

= 1

Step3:

LCM(1, 605) = 605

GCD(1, 605) = ( 1 x 605 ) / 605

= 1 / 605

= 1

So, Greatest Common Divisor of 643, 524, 629, 605 is 1
