Given numbers are 642, 945, 591, 797

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

Apply this formula for all numbers.

Step1:

LCM(642, 945) = 202230

GCD(642, 945) = ( 642 x 945 ) / 202230

= 642 / 945

= 642

Step2:

LCM(3, 591) = 591

GCD(3, 591) = ( 3 x 591 ) / 591

= 3 / 591

= 3

Step3:

LCM(3, 797) = 2391

GCD(3, 797) = ( 3 x 797 ) / 2391

= 3 / 797

= 3

So, Greatest Common Divisor of 642, 945, 591, 797 is 1
