Given numbers are 842, 631, 189, 447

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

Apply this formula for all numbers.

Step1:

LCM(842, 631) = 531302

GCD(842, 631) = ( 842 x 631 ) / 531302

= 842 / 631

= 842

Step2:

LCM(1, 189) = 189

GCD(1, 189) = ( 1 x 189 ) / 189

= 1 / 189

= 1

Step3:

LCM(1, 447) = 447

GCD(1, 447) = ( 1 x 447 ) / 447

= 1 / 447

= 1

So, Greatest Common Divisor of 842, 631, 189, 447 is 1
