Given numbers are 816, 221, 473, 130

The list of prime factors of all numbers are

Prime factors of 816 are 2 x 2 x 2 x 2 x 3 x 17

Prime factors of 221 are 13 x 17

Prime factors of 473 are 11 x 43

Prime factors of 130 are 2 x 5 x 13

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

Given numbers are 816, 221, 473, 130

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

Apply this formula for all numbers.

Step1:

LCM(816, 221) = 10608

GCD(816, 221) = ( 816 x 221 ) / 10608

= 816 / 221

= 816

Step2:

LCM(17, 473) = 8041

GCD(17, 473) = ( 17 x 473 ) / 8041

= 17 / 473

= 17

Step3:

LCM(1, 130) = 130

GCD(1, 130) = ( 1 x 130 ) / 130

= 1 / 130

= 1

So, Greatest Common Divisor of 816, 221, 473, 130 is 1
