Given numbers are 670, 916, 729, 396

The list of prime factors of all numbers are

Prime factors of 670 are 2 x 5 x 67

Prime factors of 916 are 2 x 2 x 229

Prime factors of 729 are 3 x 3 x 3 x 3 x 3 x 3

Prime factors of 396 are 2 x 2 x 3 x 3 x 11

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

Given numbers are 670, 916, 729, 396

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

Apply this formula for all numbers.

Step1:

LCM(670, 916) = 306860

GCD(670, 916) = ( 670 x 916 ) / 306860

= 670 / 916

= 670

Step2:

LCM(2, 729) = 1458

GCD(2, 729) = ( 2 x 729 ) / 1458

= 2 / 729

= 2

Step3:

LCM(1, 396) = 396

GCD(1, 396) = ( 1 x 396 ) / 396

= 1 / 396

= 1

So, Greatest Common Divisor of 670, 916, 729, 396 is 1
