Given numbers are 820, 911, 222, 155

The list of prime factors of all numbers are

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

Prime factors of 911 are 911

Prime factors of 222 are 2 x 3 x 37

Prime factors of 155 are 5 x 31

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

Given numbers are 820, 911, 222, 155

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

Apply this formula for all numbers.

Step1:

LCM(820, 911) = 747020

GCD(820, 911) = ( 820 x 911 ) / 747020

= 820 / 911

= 820

Step2:

LCM(1, 222) = 222

GCD(1, 222) = ( 1 x 222 ) / 222

= 1 / 222

= 1

Step3:

LCM(1, 155) = 155

GCD(1, 155) = ( 1 x 155 ) / 155

= 1 / 155

= 1

So, Greatest Common Divisor of 820, 911, 222, 155 is 1
