Given numbers are 655, 385, 566, 816

The list of prime factors of all numbers are

Prime factors of 655 are 5 x 131

Prime factors of 385 are 5 x 7 x 11

Prime factors of 566 are 2 x 283

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

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

Given numbers are 655, 385, 566, 816

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

Apply this formula for all numbers.

Step1:

LCM(655, 385) = 50435

GCD(655, 385) = ( 655 x 385 ) / 50435

= 655 / 385

= 655

Step2:

LCM(5, 566) = 2830

GCD(5, 566) = ( 5 x 566 ) / 2830

= 5 / 566

= 5

Step3:

LCM(1, 816) = 816

GCD(1, 816) = ( 1 x 816 ) / 816

= 1 / 816

= 1

So, Greatest Common Divisor of 655, 385, 566, 816 is 1
