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

Apply this formula for all numbers.

Step1:

LCM(495, 723) = 119295

GCD(495, 723) = ( 495 x 723 ) / 119295

= 495 / 723

= 495

Step2:

LCM(3, 258) = 258

GCD(3, 258) = ( 3 x 258 ) / 258

= 3 / 258

= 3

Step3:

LCM(3, 687) = 687

GCD(3, 687) = ( 3 x 687 ) / 687

= 3 / 687

= 3

So, Greatest Common Divisor of 495, 723, 258, 687 is 3
