Given numbers are 399, 734, 645, 528

The list of prime factors of all numbers are

Prime factors of 399 are 3 x 7 x 19

Prime factors of 734 are 2 x 367

Prime factors of 645 are 3 x 5 x 43

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

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

Given numbers are 399, 734, 645, 528

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

Apply this formula for all numbers.

Step1:

LCM(399, 734) = 292866

GCD(399, 734) = ( 399 x 734 ) / 292866

= 399 / 734

= 399

Step2:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

Step3:

LCM(1, 528) = 528

GCD(1, 528) = ( 1 x 528 ) / 528

= 1 / 528

= 1

So, Greatest Common Divisor of 399, 734, 645, 528 is 1
