Given numbers are 680, 660, 243, 358

The list of prime factors of all numbers are

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

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

Prime factors of 243 are 3 x 3 x 3 x 3 x 3

Prime factors of 358 are 2 x 179

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

Given numbers are 680, 660, 243, 358

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

Apply this formula for all numbers.

Step1:

LCM(680, 660) = 22440

GCD(680, 660) = ( 680 x 660 ) / 22440

= 680 / 660

= 680

Step2:

LCM(20, 243) = 4860

GCD(20, 243) = ( 20 x 243 ) / 4860

= 20 / 243

= 20

Step3:

LCM(1, 358) = 358

GCD(1, 358) = ( 1 x 358 ) / 358

= 1 / 358

= 1

So, Greatest Common Divisor of 680, 660, 243, 358 is 1
