Given numbers are 861, 873, 554, 408
The list of prime factors of all numbers are
Prime factors of 861 are 3 x 7 x 41
Prime factors of 873 are 3 x 3 x 97
Prime factors of 554 are 2 x 277
Prime factors of 408 are 2 x 2 x 2 x 3 x 17
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 861, 873, 554, 408
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(861, 873) = 250551
GCD(861, 873) = ( 861 x 873 ) / 250551
= 861 / 873
= 861
Step2:
LCM(3, 554) = 1662
GCD(3, 554) = ( 3 x 554 ) / 1662
= 3 / 554
= 3
Step3:
LCM(1, 408) = 408
GCD(1, 408) = ( 1 x 408 ) / 408
= 1 / 408
= 1
So, Greatest Common Divisor of 861, 873, 554, 408 is 1
