Given numbers are 841, 489, 855, 203

The list of prime factors of all numbers are

Prime factors of 841 are 29 x 29

Prime factors of 489 are 3 x 163

Prime factors of 855 are 3 x 3 x 5 x 19

Prime factors of 203 are 7 x 29

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 841, 489, 855, 203

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

Apply this formula for all numbers.

Step1:

LCM(841, 489) = 411249

GCD(841, 489) = ( 841 x 489 ) / 411249

= 841 / 489

= 841

Step2:

LCM(1, 855) = 855

GCD(1, 855) = ( 1 x 855 ) / 855

= 1 / 855

= 1

Step3:

LCM(1, 203) = 203

GCD(1, 203) = ( 1 x 203 ) / 203

= 1 / 203

= 1

So, Greatest Common Divisor of 841, 489, 855, 203 is 1
