Given numbers are 408, 388, 450, 565
The list of prime factors of all numbers are
Prime factors of 408 are 2 x 2 x 2 x 3 x 17
Prime factors of 388 are 2 x 2 x 97
Prime factors of 450 are 2 x 3 x 3 x 5 x 5
Prime factors of 565 are 5 x 113
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 408, 388, 450, 565
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(408, 388) = 39576
GCD(408, 388) = ( 408 x 388 ) / 39576
= 408 / 388
= 408
Step2:
LCM(4, 450) = 900
GCD(4, 450) = ( 4 x 450 ) / 900
= 4 / 450
= 4
Step3:
LCM(2, 565) = 1130
GCD(2, 565) = ( 2 x 565 ) / 1130
= 2 / 565
= 2
So, Greatest Common Divisor of 408, 388, 450, 565 is 1
