Given numbers are 891, 639, 233, 139

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

Apply this formula for all numbers.

Step1:

LCM(891, 639) = 63261

GCD(891, 639) = ( 891 x 639 ) / 63261

= 891 / 639

= 891

Step2:

LCM(9, 233) = 2097

GCD(9, 233) = ( 9 x 233 ) / 2097

= 9 / 233

= 9

Step3:

LCM(1, 139) = 139

GCD(1, 139) = ( 1 x 139 ) / 139

= 1 / 139

= 1

So, Greatest Common Divisor of 891, 639, 233, 139 is 1
