Given numbers are 820, 305, 576, 666

The list of prime factors of all numbers are

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

Prime factors of 305 are 5 x 61

Prime factors of 576 are 2 x 2 x 2 x 2 x 2 x 2 x 3 x 3

Prime factors of 666 are 2 x 3 x 3 x 37

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

Given numbers are 820, 305, 576, 666

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

Apply this formula for all numbers.

Step1:

LCM(820, 305) = 50020

GCD(820, 305) = ( 820 x 305 ) / 50020

= 820 / 305

= 820

Step2:

LCM(5, 576) = 2880

GCD(5, 576) = ( 5 x 576 ) / 2880

= 5 / 576

= 5

Step3:

LCM(1, 666) = 666

GCD(1, 666) = ( 1 x 666 ) / 666

= 1 / 666

= 1

So, Greatest Common Divisor of 820, 305, 576, 666 is 1
