Given numbers are 861, 541, 853, 648

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 541 are 541

Prime factors of 853 are 853

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

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

Given numbers are 861, 541, 853, 648

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

Apply this formula for all numbers.

Step1:

LCM(861, 541) = 465801

GCD(861, 541) = ( 861 x 541 ) / 465801

= 861 / 541

= 861

Step2:

LCM(1, 853) = 853

GCD(1, 853) = ( 1 x 853 ) / 853

= 1 / 853

= 1

Step3:

LCM(1, 648) = 648

GCD(1, 648) = ( 1 x 648 ) / 648

= 1 / 648

= 1

So, Greatest Common Divisor of 861, 541, 853, 648 is 1
