Given numbers are 209, 580, 666, 487

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

Apply this formula for all numbers.

Step1:

LCM(209, 580) = 121220

GCD(209, 580) = ( 209 x 580 ) / 121220

= 209 / 580

= 209

Step2:

LCM(1, 666) = 666

GCD(1, 666) = ( 1 x 666 ) / 666

= 1 / 666

= 1

Step3:

LCM(1, 487) = 487

GCD(1, 487) = ( 1 x 487 ) / 487

= 1 / 487

= 1

So, Greatest Common Divisor of 209, 580, 666, 487 is 1
