Given numbers are 405, 456, 291, 481
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 456 are 2 x 2 x 2 x 3 x 19
Prime factors of 291 are 3 x 97
Prime factors of 481 are 13 x 37
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 405, 456, 291, 481
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(405, 456) = 61560
GCD(405, 456) = ( 405 x 456 ) / 61560
= 405 / 456
= 405
Step2:
LCM(3, 291) = 291
GCD(3, 291) = ( 3 x 291 ) / 291
= 3 / 291
= 3
Step3:
LCM(3, 481) = 1443
GCD(3, 481) = ( 3 x 481 ) / 1443
= 3 / 481
= 3
So, Greatest Common Divisor of 405, 456, 291, 481 is 1
