Given numbers are 402, 545, 630, 804

The list of prime factors of all numbers are

Prime factors of 402 are 2 x 3 x 67

Prime factors of 545 are 5 x 109

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

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

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

Given numbers are 402, 545, 630, 804

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

Apply this formula for all numbers.

Step1:

LCM(402, 545) = 219090

GCD(402, 545) = ( 402 x 545 ) / 219090

= 402 / 545

= 402

Step2:

LCM(1, 630) = 630

GCD(1, 630) = ( 1 x 630 ) / 630

= 1 / 630

= 1

Step3:

LCM(1, 804) = 804

GCD(1, 804) = ( 1 x 804 ) / 804

= 1 / 804

= 1

So, Greatest Common Divisor of 402, 545, 630, 804 is 1
