Given numbers are 556, 639, 161, 893

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

Apply this formula for all numbers.

Step1:

LCM(556, 639) = 355284

GCD(556, 639) = ( 556 x 639 ) / 355284

= 556 / 639

= 556

Step2:

LCM(1, 161) = 161

GCD(1, 161) = ( 1 x 161 ) / 161

= 1 / 161

= 1

Step3:

LCM(1, 893) = 893

GCD(1, 893) = ( 1 x 893 ) / 893

= 1 / 893

= 1

So, Greatest Common Divisor of 556, 639, 161, 893 is 1
