Given numbers are 861, 516, 655, 454

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 516 are 2 x 2 x 3 x 43

Prime factors of 655 are 5 x 131

Prime factors of 454 are 2 x 227

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

Given numbers are 861, 516, 655, 454

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

Apply this formula for all numbers.

Step1:

LCM(861, 516) = 148092

GCD(861, 516) = ( 861 x 516 ) / 148092

= 861 / 516

= 861

Step2:

LCM(3, 655) = 1965

GCD(3, 655) = ( 3 x 655 ) / 1965

= 3 / 655

= 3

Step3:

LCM(1, 454) = 454

GCD(1, 454) = ( 1 x 454 ) / 454

= 1 / 454

= 1

So, Greatest Common Divisor of 861, 516, 655, 454 is 1
