Given numbers are 861, 530, 409, 536

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 530 are 2 x 5 x 53

Prime factors of 409 are 409

Prime factors of 536 are 2 x 2 x 2 x 67

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

Given numbers are 861, 530, 409, 536

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

Apply this formula for all numbers.

Step1:

LCM(861, 530) = 456330

GCD(861, 530) = ( 861 x 530 ) / 456330

= 861 / 530

= 861

Step2:

LCM(1, 409) = 409

GCD(1, 409) = ( 1 x 409 ) / 409

= 1 / 409

= 1

Step3:

LCM(1, 536) = 536

GCD(1, 536) = ( 1 x 536 ) / 536

= 1 / 536

= 1

So, Greatest Common Divisor of 861, 530, 409, 536 is 1
