Given numbers are 408, 287, 297, 417
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(408, 287) = 117096
GCD(408, 287) = ( 408 x 287 ) / 117096
= 408 / 287
= 408
Step2:
LCM(1, 297) = 297
GCD(1, 297) = ( 1 x 297 ) / 297
= 1 / 297
= 1
Step3:
LCM(1, 417) = 417
GCD(1, 417) = ( 1 x 417 ) / 417
= 1 / 417
= 1
So, Greatest Common Divisor of 408, 287, 297, 417 is 1
