Given numbers are 555, 989, 251, 163

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

Apply this formula for all numbers.

Step1:

LCM(555, 989) = 548895

GCD(555, 989) = ( 555 x 989 ) / 548895

= 555 / 989

= 555

Step2:

LCM(1, 251) = 251

GCD(1, 251) = ( 1 x 251 ) / 251

= 1 / 251

= 1

Step3:

LCM(1, 163) = 163

GCD(1, 163) = ( 1 x 163 ) / 163

= 1 / 163

= 1

So, Greatest Common Divisor of 555, 989, 251, 163 is 1
