Given numbers are 278, 398, 845, 397

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

Apply this formula for all numbers.

Step1:

LCM(278, 398) = 55322

GCD(278, 398) = ( 278 x 398 ) / 55322

= 278 / 398

= 278

Step2:

LCM(2, 845) = 1690

GCD(2, 845) = ( 2 x 845 ) / 1690

= 2 / 845

= 2

Step3:

LCM(1, 397) = 397

GCD(1, 397) = ( 1 x 397 ) / 397

= 1 / 397

= 1

So, Greatest Common Divisor of 278, 398, 845, 397 is 1
