Given numbers are 640, 630, 69, 804

The list of prime factors of all numbers are

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

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

Prime factors of 69 are 3 x 23

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 640, 630, 69, 804

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

Apply this formula for all numbers.

Step1:

LCM(640, 630) = 40320

GCD(640, 630) = ( 640 x 630 ) / 40320

= 640 / 630

= 640

Step2:

LCM(10, 69) = 690

GCD(10, 69) = ( 10 x 69 ) / 690

= 10 / 69

= 10

Step3:

LCM(1, 804) = 804

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

= 1 / 804

= 1

So, Greatest Common Divisor of 640, 630, 69, 804 is 1
