Given numbers are 455, 287, 717, 671
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(455, 287) = 18655
GCD(455, 287) = ( 455 x 287 ) / 18655
= 455 / 287
= 455
Step2:
LCM(7, 717) = 5019
GCD(7, 717) = ( 7 x 717 ) / 5019
= 7 / 717
= 7
Step3:
LCM(1, 671) = 671
GCD(1, 671) = ( 1 x 671 ) / 671
= 1 / 671
= 1
So, Greatest Common Divisor of 455, 287, 717, 671 is 1
