Given numbers are 512, 780, 425, 820

The list of prime factors of all numbers are

Prime factors of 512 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 425 are 5 x 5 x 17

Prime factors of 820 are 2 x 2 x 5 x 41

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

Given numbers are 512, 780, 425, 820

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

Apply this formula for all numbers.

Step1:

LCM(512, 780) = 99840

GCD(512, 780) = ( 512 x 780 ) / 99840

= 512 / 780

= 512

Step2:

LCM(4, 425) = 1700

GCD(4, 425) = ( 4 x 425 ) / 1700

= 4 / 425

= 4

Step3:

LCM(1, 820) = 820

GCD(1, 820) = ( 1 x 820 ) / 820

= 1 / 820

= 1

So, Greatest Common Divisor of 512, 780, 425, 820 is 1
