Given numbers are 215, 403, 805, 694

The list of prime factors of all numbers are

Prime factors of 215 are 5 x 43

Prime factors of 403 are 13 x 31

Prime factors of 805 are 5 x 7 x 23

Prime factors of 694 are 2 x 347

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

Given numbers are 215, 403, 805, 694

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

Apply this formula for all numbers.

Step1:

LCM(215, 403) = 86645

GCD(215, 403) = ( 215 x 403 ) / 86645

= 215 / 403

= 215

Step2:

LCM(1, 805) = 805

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

= 1 / 805

= 1

Step3:

LCM(1, 694) = 694

GCD(1, 694) = ( 1 x 694 ) / 694

= 1 / 694

= 1

So, Greatest Common Divisor of 215, 403, 805, 694 is 1
