So, the GCD (840, 861, 37, 956) = 1.

Given numbers are 840, 861, 37, 956

The list of prime factors of all numbers are

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 861 are 3 x 7 x 41

Prime factors of 37 are 37

Prime factors of 956 are 2 x 2 x 239

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

Given numbers are 840, 861, 37, 956

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

Apply this formula for all numbers.

Step1:

LCM(840, 861) = 34440

GCD(840, 861) = ( 840 x 861 ) / 34440

= 840 / 861

= 840

Step2:

LCM(21, 37) = 777

GCD(21, 37) = ( 21 x 37 ) / 777

= 21 / 37

= 21

Step3:

LCM(1, 956) = 956

GCD(1, 956) = ( 1 x 956 ) / 956

= 1 / 956

= 1

So, Greatest Common Divisor of 840, 861, 37, 956 is 1
