Given numbers are 804, 630, 693, 455

The list of prime factors of all numbers are

Prime factors of 804 are 2 x 2 x 3 x 67

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

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

Prime factors of 455 are 5 x 7 x 13

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

Given numbers are 804, 630, 693, 455

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

Apply this formula for all numbers.

Step1:

LCM(804, 630) = 84420

GCD(804, 630) = ( 804 x 630 ) / 84420

= 804 / 630

= 804

Step2:

LCM(6, 693) = 1386

GCD(6, 693) = ( 6 x 693 ) / 1386

= 6 / 693

= 6

Step3:

LCM(3, 455) = 1365

GCD(3, 455) = ( 3 x 455 ) / 1365

= 3 / 455

= 3

So, Greatest Common Divisor of 804, 630, 693, 455 is 1
