Given numbers are 842, 639, 153, 230

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

Apply this formula for all numbers.

Step1:

LCM(842, 639) = 538038

GCD(842, 639) = ( 842 x 639 ) / 538038

= 842 / 639

= 842

Step2:

LCM(1, 153) = 153

GCD(1, 153) = ( 1 x 153 ) / 153

= 1 / 153

= 1

Step3:

LCM(1, 230) = 230

GCD(1, 230) = ( 1 x 230 ) / 230

= 1 / 230

= 1

So, Greatest Common Divisor of 842, 639, 153, 230 is 1
