Given numbers are 550, 861, 511, 820

The list of prime factors of all numbers are

Prime factors of 550 are 2 x 5 x 5 x 11

Prime factors of 861 are 3 x 7 x 41

Prime factors of 511 are 7 x 73

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 550, 861, 511, 820

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

Apply this formula for all numbers.

Step1:

LCM(550, 861) = 473550

GCD(550, 861) = ( 550 x 861 ) / 473550

= 550 / 861

= 550

Step2:

LCM(1, 511) = 511

GCD(1, 511) = ( 1 x 511 ) / 511

= 1 / 511

= 1

Step3:

LCM(1, 820) = 820

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

= 1 / 820

= 1

So, Greatest Common Divisor of 550, 861, 511, 820 is 1
