Given numbers are 699, 690, 361, 209

The list of prime factors of all numbers are

Prime factors of 699 are 3 x 233

Prime factors of 690 are 2 x 3 x 5 x 23

Prime factors of 361 are 19 x 19

Prime factors of 209 are 11 x 19

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

Given numbers are 699, 690, 361, 209

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

Apply this formula for all numbers.

Step1:

LCM(699, 690) = 160770

GCD(699, 690) = ( 699 x 690 ) / 160770

= 699 / 690

= 699

Step2:

LCM(3, 361) = 1083

GCD(3, 361) = ( 3 x 361 ) / 1083

= 3 / 361

= 3

Step3:

LCM(1, 209) = 209

GCD(1, 209) = ( 1 x 209 ) / 209

= 1 / 209

= 1

So, Greatest Common Divisor of 699, 690, 361, 209 is 1
