Given numbers are 685, 747, 693, 330

The list of prime factors of all numbers are

Prime factors of 685 are 5 x 137

Prime factors of 747 are 3 x 3 x 83

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

Prime factors of 330 are 2 x 3 x 5 x 11

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

Given numbers are 685, 747, 693, 330

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

Apply this formula for all numbers.

Step1:

LCM(685, 747) = 511695

GCD(685, 747) = ( 685 x 747 ) / 511695

= 685 / 747

= 685

Step2:

LCM(1, 693) = 693

GCD(1, 693) = ( 1 x 693 ) / 693

= 1 / 693

= 1

Step3:

LCM(1, 330) = 330

GCD(1, 330) = ( 1 x 330 ) / 330

= 1 / 330

= 1

So, Greatest Common Divisor of 685, 747, 693, 330 is 1
