Given numbers are 405, 160, 374, 404
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 160 are 2 x 2 x 2 x 2 x 2 x 5
Prime factors of 374 are 2 x 11 x 17
Prime factors of 404 are 2 x 2 x 101
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 405, 160, 374, 404
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(405, 160) = 12960
GCD(405, 160) = ( 405 x 160 ) / 12960
= 405 / 160
= 405
Step2:
LCM(5, 374) = 1870
GCD(5, 374) = ( 5 x 374 ) / 1870
= 5 / 374
= 5
Step3:
LCM(1, 404) = 404
GCD(1, 404) = ( 1 x 404 ) / 404
= 1 / 404
= 1
So, Greatest Common Divisor of 405, 160, 374, 404 is 1
