Given numbers are 102, 206, 565, 980

The list of prime factors of all numbers are

Prime factors of 102 are 2 x 3 x 17

Prime factors of 206 are 2 x 103

Prime factors of 565 are 5 x 113

Prime factors of 980 are 2 x 2 x 5 x 7 x 7

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

Given numbers are 102, 206, 565, 980

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

Apply this formula for all numbers.

Step1:

LCM(102, 206) = 10506

GCD(102, 206) = ( 102 x 206 ) / 10506

= 102 / 206

= 102

Step2:

LCM(2, 565) = 1130

GCD(2, 565) = ( 2 x 565 ) / 1130

= 2 / 565

= 2

Step3:

LCM(1, 980) = 980

GCD(1, 980) = ( 1 x 980 ) / 980

= 1 / 980

= 1

So, Greatest Common Divisor of 102, 206, 565, 980 is 1
