Given numbers are 398, 909, 951, 381

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

Apply this formula for all numbers.

Step1:

LCM(398, 909) = 361782

GCD(398, 909) = ( 398 x 909 ) / 361782

= 398 / 909

= 398

Step2:

LCM(1, 951) = 951

GCD(1, 951) = ( 1 x 951 ) / 951

= 1 / 951

= 1

Step3:

LCM(1, 381) = 381

GCD(1, 381) = ( 1 x 381 ) / 381

= 1 / 381

= 1

So, Greatest Common Divisor of 398, 909, 951, 381 is 1
