The list of prime factors of all numbers are
Prime factors of 485 are 5 x 97
Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5
Prime factors of 407 are 11 x 37
Prime factors of 164 are 2 x 2 x 41
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 485, 720, 407, 164
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(485, 720) = 69840
GCD(485, 720) = ( 485 x 720 ) / 69840
= 485 / 720
= 485
Step2:
LCM(5, 407) = 2035
GCD(5, 407) = ( 5 x 407 ) / 2035
= 5 / 407
= 5
Step3:
LCM(1, 164) = 164
GCD(1, 164) = ( 1 x 164 ) / 164
= 1 / 164
= 1
So, Greatest Common Divisor of 485, 720, 407, 164 is 1
