Given numbers are 349, 770, 658, 640

The list of prime factors of all numbers are

Prime factors of 349 are 349

Prime factors of 770 are 2 x 5 x 7 x 11

Prime factors of 658 are 2 x 7 x 47

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

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

Given numbers are 349, 770, 658, 640

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

Apply this formula for all numbers.

Step1:

LCM(349, 770) = 268730

GCD(349, 770) = ( 349 x 770 ) / 268730

= 349 / 770

= 349

Step2:

LCM(1, 658) = 658

GCD(1, 658) = ( 1 x 658 ) / 658

= 1 / 658

= 1

Step3:

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

= 1 / 640

= 1

So, Greatest Common Divisor of 349, 770, 658, 640 is 1
