Given numbers are 206, 568, 402, 639

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

Apply this formula for all numbers.

Step1:

LCM(206, 568) = 58504

GCD(206, 568) = ( 206 x 568 ) / 58504

= 206 / 568

= 206

Step2:

LCM(2, 402) = 402

GCD(2, 402) = ( 2 x 402 ) / 402

= 2 / 402

= 2

Step3:

LCM(2, 639) = 1278

GCD(2, 639) = ( 2 x 639 ) / 1278

= 2 / 639

= 2

So, Greatest Common Divisor of 206, 568, 402, 639 is 1
