Given numbers are 495, 820, 645, 693

The list of prime factors of all numbers are

Prime factors of 495 are 3 x 3 x 5 x 11

Prime factors of 820 are 2 x 2 x 5 x 41

Prime factors of 645 are 3 x 5 x 43

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

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

Given numbers are 495, 820, 645, 693

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

Apply this formula for all numbers.

Step1:

LCM(495, 820) = 81180

GCD(495, 820) = ( 495 x 820 ) / 81180

= 495 / 820

= 495

Step2:

LCM(5, 645) = 645

GCD(5, 645) = ( 5 x 645 ) / 645

= 5 / 645

= 5

Step3:

LCM(5, 693) = 3465

GCD(5, 693) = ( 5 x 693 ) / 3465

= 5 / 693

= 5

So, Greatest Common Divisor of 495, 820, 645, 693 is 1
