Given numbers are 693, 651, 705, 428

The list of prime factors of all numbers are

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

Prime factors of 651 are 3 x 7 x 31

Prime factors of 705 are 3 x 5 x 47

Prime factors of 428 are 2 x 2 x 107

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

Given numbers are 693, 651, 705, 428

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

Apply this formula for all numbers.

Step1:

LCM(693, 651) = 21483

GCD(693, 651) = ( 693 x 651 ) / 21483

= 693 / 651

= 693

Step2:

LCM(21, 705) = 4935

GCD(21, 705) = ( 21 x 705 ) / 4935

= 21 / 705

= 21

Step3:

LCM(3, 428) = 1284

GCD(3, 428) = ( 3 x 428 ) / 1284

= 3 / 428

= 3

So, Greatest Common Divisor of 693, 651, 705, 428 is 1
