Given numbers are 645, 568, 557, 694

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

Apply this formula for all numbers.

Step1:

LCM(645, 568) = 366360

GCD(645, 568) = ( 645 x 568 ) / 366360

= 645 / 568

= 645

Step2:

LCM(1, 557) = 557

GCD(1, 557) = ( 1 x 557 ) / 557

= 1 / 557

= 1

Step3:

LCM(1, 694) = 694

GCD(1, 694) = ( 1 x 694 ) / 694

= 1 / 694

= 1

So, Greatest Common Divisor of 645, 568, 557, 694 is 1
