Given numbers are 398, 455, 958

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

Apply this formula for all numbers.

Step1:

LCM(398, 455) = 181090

GCD(398, 455) = ( 398 x 455 ) / 181090

= 398 / 455

= 398

Step2:

LCM(1, 958) = 958

GCD(1, 958) = ( 1 x 958 ) / 958

= 1 / 958

= 1

So, Greatest Common Divisor of 398, 455, 958 is 1
