Given numbers are 861, 506, 197, 370

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 506 are 2 x 11 x 23

Prime factors of 197 are 197

Prime factors of 370 are 2 x 5 x 37

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

Given numbers are 861, 506, 197, 370

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

Apply this formula for all numbers.

Step1:

LCM(861, 506) = 435666

GCD(861, 506) = ( 861 x 506 ) / 435666

= 861 / 506

= 861

Step2:

LCM(1, 197) = 197

GCD(1, 197) = ( 1 x 197 ) / 197

= 1 / 197

= 1

Step3:

LCM(1, 370) = 370

GCD(1, 370) = ( 1 x 370 ) / 370

= 1 / 370

= 1

So, Greatest Common Divisor of 861, 506, 197, 370 is 1
