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

Given numbers are 669, 390, 612, 409

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

Apply this formula for all numbers.

Step1:

LCM(669, 390) = 86970

GCD(669, 390) = ( 669 x 390 ) / 86970

= 669 / 390

= 669

Step2:

LCM(3, 612) = 612

GCD(3, 612) = ( 3 x 612 ) / 612

= 3 / 612

= 3

Step3:

LCM(3, 409) = 1227

GCD(3, 409) = ( 3 x 409 ) / 1227

= 3 / 409

= 3

So, Greatest Common Divisor of 669, 390, 612, 409 is 1
