Given numbers are 398, 178, 868, 567

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

Apply this formula for all numbers.

Step1:

LCM(398, 178) = 35422

GCD(398, 178) = ( 398 x 178 ) / 35422

= 398 / 178

= 398

Step2:

LCM(2, 868) = 868

GCD(2, 868) = ( 2 x 868 ) / 868

= 2 / 868

= 2

Step3:

LCM(2, 567) = 1134

GCD(2, 567) = ( 2 x 567 ) / 1134

= 2 / 567

= 2

So, Greatest Common Divisor of 398, 178, 868, 567 is 1
