Given numbers are 514, 780, 392, 618

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

Apply this formula for all numbers.

Step1:

LCM(514, 780) = 200460

GCD(514, 780) = ( 514 x 780 ) / 200460

= 514 / 780

= 514

Step2:

LCM(2, 392) = 392

GCD(2, 392) = ( 2 x 392 ) / 392

= 2 / 392

= 2

Step3:

LCM(2, 618) = 618

GCD(2, 618) = ( 2 x 618 ) / 618

= 2 / 618

= 2

So, Greatest Common Divisor of 514, 780, 392, 618 is 2
