Given numbers are 861, 816, 841, 542

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 816 are 2 x 2 x 2 x 2 x 3 x 17

Prime factors of 841 are 29 x 29

Prime factors of 542 are 2 x 271

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

Given numbers are 861, 816, 841, 542

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

Apply this formula for all numbers.

Step1:

LCM(861, 816) = 234192

GCD(861, 816) = ( 861 x 816 ) / 234192

= 861 / 816

= 861

Step2:

LCM(3, 841) = 2523

GCD(3, 841) = ( 3 x 841 ) / 2523

= 3 / 841

= 3

Step3:

LCM(1, 542) = 542

GCD(1, 542) = ( 1 x 542 ) / 542

= 1 / 542

= 1

So, Greatest Common Divisor of 861, 816, 841, 542 is 1
