The list of prime factors of all numbers are
Prime factors of 405 are 3 x 3 x 3 x 3 x 5
Prime factors of 308 are 2 x 2 x 7 x 11
Prime factors of 711 are 3 x 3 x 79
Prime factors of 275 are 5 x 5 x 11
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 405, 308, 711, 275
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(405, 308) = 124740
GCD(405, 308) = ( 405 x 308 ) / 124740
= 405 / 308
= 405
Step2:
LCM(1, 711) = 711
GCD(1, 711) = ( 1 x 711 ) / 711
= 1 / 711
= 1
Step3:
LCM(1, 275) = 275
GCD(1, 275) = ( 1 x 275 ) / 275
= 1 / 275
= 1
So, Greatest Common Divisor of 405, 308, 711, 275 is 1
