Given numbers are 680, 493, 845, 355

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

Apply this formula for all numbers.

Step1:

LCM(680, 493) = 19720

GCD(680, 493) = ( 680 x 493 ) / 19720

= 680 / 493

= 680

Step2:

LCM(17, 845) = 14365

GCD(17, 845) = ( 17 x 845 ) / 14365

= 17 / 845

= 17

Step3:

LCM(1, 355) = 355

GCD(1, 355) = ( 1 x 355 ) / 355

= 1 / 355

= 1

So, Greatest Common Divisor of 680, 493, 845, 355 is 1
