Given numbers are 820, 408, 861, 541

The list of prime factors of all numbers are

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

Prime factors of 408 are 2 x 2 x 2 x 3 x 17

Prime factors of 861 are 3 x 7 x 41

Prime factors of 541 are 541

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

Given numbers are 820, 408, 861, 541

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

Apply this formula for all numbers.

Step1:

LCM(820, 408) = 83640

GCD(820, 408) = ( 820 x 408 ) / 83640

= 820 / 408

= 820

Step2:

LCM(4, 861) = 3444

GCD(4, 861) = ( 4 x 861 ) / 3444

= 4 / 861

= 4

Step3:

LCM(1, 541) = 541

GCD(1, 541) = ( 1 x 541 ) / 541

= 1 / 541

= 1

So, Greatest Common Divisor of 820, 408, 861, 541 is 1
