Given numbers are 660, 657, 869, 329

The list of prime factors of all numbers are

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

Prime factors of 657 are 3 x 3 x 73

Prime factors of 869 are 11 x 79

Prime factors of 329 are 7 x 47

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

Given numbers are 660, 657, 869, 329

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

Apply this formula for all numbers.

Step1:

LCM(660, 657) = 144540

GCD(660, 657) = ( 660 x 657 ) / 144540

= 660 / 657

= 660

Step2:

LCM(3, 869) = 2607

GCD(3, 869) = ( 3 x 869 ) / 2607

= 3 / 869

= 3

Step3:

LCM(1, 329) = 329

GCD(1, 329) = ( 1 x 329 ) / 329

= 1 / 329

= 1

So, Greatest Common Divisor of 660, 657, 869, 329 is 1
