Given numbers are 102, 697, 660, 261

The list of prime factors of all numbers are

Prime factors of 102 are 2 x 3 x 17

Prime factors of 697 are 17 x 41

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 261 are 3 x 3 x 29

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

Given numbers are 102, 697, 660, 261

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

Apply this formula for all numbers.

Step1:

LCM(102, 697) = 4182

GCD(102, 697) = ( 102 x 697 ) / 4182

= 102 / 697

= 102

Step2:

LCM(17, 660) = 11220

GCD(17, 660) = ( 17 x 660 ) / 11220

= 17 / 660

= 17

Step3:

LCM(1, 261) = 261

GCD(1, 261) = ( 1 x 261 ) / 261

= 1 / 261

= 1

So, Greatest Common Divisor of 102, 697, 660, 261 is 1
