The list of prime factors of all numbers are

Prime factors of 707 are 7 x 101

Prime factors of 435 are 3 x 5 x 29

Prime factors of 656 are 2 x 2 x 2 x 2 x 41

Prime factors of 398 are 2 x 199

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

Given numbers are 707, 435, 656, 398

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

Apply this formula for all numbers.

Step1:

LCM(707, 435) = 307545

GCD(707, 435) = ( 707 x 435 ) / 307545

= 707 / 435

= 707

Step2:

LCM(1, 656) = 656

GCD(1, 656) = ( 1 x 656 ) / 656

= 1 / 656

= 1

Step3:

LCM(1, 398) = 398

GCD(1, 398) = ( 1 x 398 ) / 398

= 1 / 398

= 1

So, Greatest Common Divisor of 707, 435, 656, 398 is 1
