Given numbers are 278, 482, 389, 189

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

Apply this formula for all numbers.

Step1:

LCM(278, 482) = 66998

GCD(278, 482) = ( 278 x 482 ) / 66998

= 278 / 482

= 278

Step2:

LCM(2, 389) = 778

GCD(2, 389) = ( 2 x 389 ) / 778

= 2 / 389

= 2

Step3:

LCM(1, 189) = 189

GCD(1, 189) = ( 1 x 189 ) / 189

= 1 / 189

= 1

So, Greatest Common Divisor of 278, 482, 389, 189 is 1
