Given numbers are 678, 393, 485, 457

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

Apply this formula for all numbers.

Step1:

LCM(678, 393) = 88818

GCD(678, 393) = ( 678 x 393 ) / 88818

= 678 / 393

= 678

Step2:

LCM(3, 485) = 1455

GCD(3, 485) = ( 3 x 485 ) / 1455

= 3 / 485

= 3

Step3:

LCM(1, 457) = 457

GCD(1, 457) = ( 1 x 457 ) / 457

= 1 / 457

= 1

So, Greatest Common Divisor of 678, 393, 485, 457 is 1
