The list of prime factors of all numbers are
Prime factors of 805 are 5 x 7 x 23
Prime factors of 131 are 131
Prime factors of 322 are 2 x 7 x 23
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 805, 131, 322, 648
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(805, 131) = 105455
GCD(805, 131) = ( 805 x 131 ) / 105455
= 805 / 131
= 805
Step2:
LCM(1, 322) = 322
GCD(1, 322) = ( 1 x 322 ) / 322
= 1 / 322
= 1
Step3:
LCM(1, 648) = 648
GCD(1, 648) = ( 1 x 648 ) / 648
= 1 / 648
= 1
So, Greatest Common Divisor of 805, 131, 322, 648 is 1
