Given numbers are 690, 447, 519, 689

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

Apply this formula for all numbers.

Step1:

LCM(690, 447) = 102810

GCD(690, 447) = ( 690 x 447 ) / 102810

= 690 / 447

= 690

Step2:

LCM(3, 519) = 519

GCD(3, 519) = ( 3 x 519 ) / 519

= 3 / 519

= 3

Step3:

LCM(3, 689) = 2067

GCD(3, 689) = ( 3 x 689 ) / 2067

= 3 / 689

= 3

So, Greatest Common Divisor of 690, 447, 519, 689 is 1
