Given numbers are 820, 420, 881, 553

The list of prime factors of all numbers are

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

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 881 are 881

Prime factors of 553 are 7 x 79

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

Given numbers are 820, 420, 881, 553

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

Apply this formula for all numbers.

Step1:

LCM(820, 420) = 17220

GCD(820, 420) = ( 820 x 420 ) / 17220

= 820 / 420

= 820

Step2:

LCM(20, 881) = 17620

GCD(20, 881) = ( 20 x 881 ) / 17620

= 20 / 881

= 20

Step3:

LCM(1, 553) = 553

GCD(1, 553) = ( 1 x 553 ) / 553

= 1 / 553

= 1

So, Greatest Common Divisor of 820, 420, 881, 553 is 1
