Given numbers are 398, 332, 347, 561

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

Apply this formula for all numbers.

Step1:

LCM(398, 332) = 66068

GCD(398, 332) = ( 398 x 332 ) / 66068

= 398 / 332

= 398

Step2:

LCM(2, 347) = 694

GCD(2, 347) = ( 2 x 347 ) / 694

= 2 / 347

= 2

Step3:

LCM(1, 561) = 561

GCD(1, 561) = ( 1 x 561 ) / 561

= 1 / 561

= 1

So, Greatest Common Divisor of 398, 332, 347, 561 is 1
