Given numbers are 620, 395, 528, 729

The list of prime factors of all numbers are

Prime factors of 620 are 2 x 2 x 5 x 31

Prime factors of 395 are 5 x 79

Prime factors of 528 are 2 x 2 x 2 x 2 x 3 x 11

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

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

Given numbers are 620, 395, 528, 729

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

Apply this formula for all numbers.

Step1:

LCM(620, 395) = 48980

GCD(620, 395) = ( 620 x 395 ) / 48980

= 620 / 395

= 620

Step2:

LCM(5, 528) = 2640

GCD(5, 528) = ( 5 x 528 ) / 2640

= 5 / 528

= 5

Step3:

LCM(1, 729) = 729

GCD(1, 729) = ( 1 x 729 ) / 729

= 1 / 729

= 1

So, Greatest Common Divisor of 620, 395, 528, 729 is 1
