Given numbers are 804, 645, 660, 772

The list of prime factors of all numbers are

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

Prime factors of 645 are 3 x 5 x 43

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 772 are 2 x 2 x 193

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

Given numbers are 804, 645, 660, 772

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

Apply this formula for all numbers.

Step1:

LCM(804, 645) = 172860

GCD(804, 645) = ( 804 x 645 ) / 172860

= 804 / 645

= 804

Step2:

LCM(3, 660) = 660

GCD(3, 660) = ( 3 x 660 ) / 660

= 3 / 660

= 3

Step3:

LCM(3, 772) = 2316

GCD(3, 772) = ( 3 x 772 ) / 2316

= 3 / 772

= 3

So, Greatest Common Divisor of 804, 645, 660, 772 is 1
