Given numbers are 567, 645, 857, 789

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

Apply this formula for all numbers.

Step1:

LCM(567, 645) = 121905

GCD(567, 645) = ( 567 x 645 ) / 121905

= 567 / 645

= 567

Step2:

LCM(3, 857) = 2571

GCD(3, 857) = ( 3 x 857 ) / 2571

= 3 / 857

= 3

Step3:

LCM(1, 789) = 789

GCD(1, 789) = ( 1 x 789 ) / 789

= 1 / 789

= 1

So, Greatest Common Divisor of 567, 645, 857, 789 is 1
