Given numbers are 690, 318, 209, 554

The list of prime factors of all numbers are

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

Prime factors of 318 are 2 x 3 x 53

Prime factors of 209 are 11 x 19

Prime factors of 554 are 2 x 277

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

Given numbers are 690, 318, 209, 554

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

Apply this formula for all numbers.

Step1:

LCM(690, 318) = 36570

GCD(690, 318) = ( 690 x 318 ) / 36570

= 690 / 318

= 690

Step2:

LCM(6, 209) = 1254

GCD(6, 209) = ( 6 x 209 ) / 1254

= 6 / 209

= 6

Step3:

LCM(1, 554) = 554

GCD(1, 554) = ( 1 x 554 ) / 554

= 1 / 554

= 1

So, Greatest Common Divisor of 690, 318, 209, 554 is 1
