Given numbers are 861, 620, 838, 974

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 620 are 2 x 2 x 5 x 31

Prime factors of 838 are 2 x 419

Prime factors of 974 are 2 x 487

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

Given numbers are 861, 620, 838, 974

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

Apply this formula for all numbers.

Step1:

LCM(861, 620) = 533820

GCD(861, 620) = ( 861 x 620 ) / 533820

= 861 / 620

= 861

Step2:

LCM(1, 838) = 838

GCD(1, 838) = ( 1 x 838 ) / 838

= 1 / 838

= 1

Step3:

LCM(1, 974) = 974

GCD(1, 974) = ( 1 x 974 ) / 974

= 1 / 974

= 1

So, Greatest Common Divisor of 861, 620, 838, 974 is 1
