The list of prime factors of all numbers are

Prime factors of 217 are 7 x 31

Prime factors of 639 are 3 x 3 x 71

Prime factors of 801 are 3 x 3 x 89

Prime factors of 206 are 2 x 103

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

Given numbers are 217, 639, 801, 206

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

Apply this formula for all numbers.

Step1:

LCM(217, 639) = 138663

GCD(217, 639) = ( 217 x 639 ) / 138663

= 217 / 639

= 217

Step2:

LCM(1, 801) = 801

GCD(1, 801) = ( 1 x 801 ) / 801

= 1 / 801

= 1

Step3:

LCM(1, 206) = 206

GCD(1, 206) = ( 1 x 206 ) / 206

= 1 / 206

= 1

So, Greatest Common Divisor of 217, 639, 801, 206 is 1
