Given numbers are 861, 225, 156, 818

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 225 are 3 x 3 x 5 x 5

Prime factors of 156 are 2 x 2 x 3 x 13

Prime factors of 818 are 2 x 409

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

Given numbers are 861, 225, 156, 818

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

Apply this formula for all numbers.

Step1:

LCM(861, 225) = 64575

GCD(861, 225) = ( 861 x 225 ) / 64575

= 861 / 225

= 861

Step2:

LCM(3, 156) = 156

GCD(3, 156) = ( 3 x 156 ) / 156

= 3 / 156

= 3

Step3:

LCM(3, 818) = 2454

GCD(3, 818) = ( 3 x 818 ) / 2454

= 3 / 818

= 3

So, Greatest Common Divisor of 861, 225, 156, 818 is 1
