Given numbers are 393, 363, 778, 487

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

Apply this formula for all numbers.

Step1:

LCM(393, 363) = 47553

GCD(393, 363) = ( 393 x 363 ) / 47553

= 393 / 363

= 393

Step2:

LCM(3, 778) = 2334

GCD(3, 778) = ( 3 x 778 ) / 2334

= 3 / 778

= 3

Step3:

LCM(1, 487) = 487

GCD(1, 487) = ( 1 x 487 ) / 487

= 1 / 487

= 1

So, Greatest Common Divisor of 393, 363, 778, 487 is 1
