Given numbers are 398, 958, 902, 397

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

Apply this formula for all numbers.

Step1:

LCM(398, 958) = 190642

GCD(398, 958) = ( 398 x 958 ) / 190642

= 398 / 958

= 398

Step2:

LCM(2, 902) = 902

GCD(2, 902) = ( 2 x 902 ) / 902

= 2 / 902

= 2

Step3:

LCM(2, 397) = 794

GCD(2, 397) = ( 2 x 397 ) / 794

= 2 / 397

= 2

So, Greatest Common Divisor of 398, 958, 902, 397 is 1
