Given numbers are 646, 693, 388, 525

The list of prime factors of all numbers are

Prime factors of 646 are 2 x 17 x 19

Prime factors of 693 are 3 x 3 x 7 x 11

Prime factors of 388 are 2 x 2 x 97

Prime factors of 525 are 3 x 5 x 5 x 7

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

Given numbers are 646, 693, 388, 525

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

Apply this formula for all numbers.

Step1:

LCM(646, 693) = 447678

GCD(646, 693) = ( 646 x 693 ) / 447678

= 646 / 693

= 646

Step2:

LCM(1, 388) = 388

GCD(1, 388) = ( 1 x 388 ) / 388

= 1 / 388

= 1

Step3:

LCM(1, 525) = 525

GCD(1, 525) = ( 1 x 525 ) / 525

= 1 / 525

= 1

So, Greatest Common Divisor of 646, 693, 388, 525 is 1
