Given numbers are 455, 975, 398, 909

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(455, 975) = 6825

GCD(455, 975) = ( 455 x 975 ) / 6825

= 455 / 975

= 455

Step2:

LCM(65, 398) = 25870

GCD(65, 398) = ( 65 x 398 ) / 25870

= 65 / 398

= 65

Step3:

LCM(1, 909) = 909

GCD(1, 909) = ( 1 x 909 ) / 909

= 1 / 909

= 1

So, Greatest Common Divisor of 455, 975, 398, 909 is 1
