Given numbers are 668, 755, 805, 216

The list of prime factors of all numbers are

Prime factors of 668 are 2 x 2 x 167

Prime factors of 755 are 5 x 151

Prime factors of 805 are 5 x 7 x 23

Prime factors of 216 are 2 x 2 x 2 x 3 x 3 x 3

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

Given numbers are 668, 755, 805, 216

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

Apply this formula for all numbers.

Step1:

LCM(668, 755) = 504340

GCD(668, 755) = ( 668 x 755 ) / 504340

= 668 / 755

= 668

Step2:

LCM(1, 805) = 805

GCD(1, 805) = ( 1 x 805 ) / 805

= 1 / 805

= 1

Step3:

LCM(1, 216) = 216

GCD(1, 216) = ( 1 x 216 ) / 216

= 1 / 216

= 1

So, Greatest Common Divisor of 668, 755, 805, 216 is 1
