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

Apply this formula for all numbers.

Step1:

LCM(393, 657) = 86067

GCD(393, 657) = ( 393 x 657 ) / 86067

= 393 / 657

= 393

Step2:

LCM(3, 629) = 1887

GCD(3, 629) = ( 3 x 629 ) / 1887

= 3 / 629

= 3

Step3:

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

= 1 / 640

= 1

So, Greatest Common Divisor of 393, 657, 629, 640 is 1
