Given numbers are 861, 943, 665, 616

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 943 are 23 x 41

Prime factors of 665 are 5 x 7 x 19

Prime factors of 616 are 2 x 2 x 2 x 7 x 11

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

Given numbers are 861, 943, 665, 616

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

Apply this formula for all numbers.

Step1:

LCM(861, 943) = 19803

GCD(861, 943) = ( 861 x 943 ) / 19803

= 861 / 943

= 861

Step2:

LCM(41, 665) = 27265

GCD(41, 665) = ( 41 x 665 ) / 27265

= 41 / 665

= 41

Step3:

LCM(1, 616) = 616

GCD(1, 616) = ( 1 x 616 ) / 616

= 1 / 616

= 1

So, Greatest Common Divisor of 861, 943, 665, 616 is 1
