Given numbers are 399, 197, 905, 949

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

Apply this formula for all numbers.

Step1:

LCM(399, 197) = 78603

GCD(399, 197) = ( 399 x 197 ) / 78603

= 399 / 197

= 399

Step2:

LCM(1, 905) = 905

GCD(1, 905) = ( 1 x 905 ) / 905

= 1 / 905

= 1

Step3:

LCM(1, 949) = 949

GCD(1, 949) = ( 1 x 949 ) / 949

= 1 / 949

= 1

So, Greatest Common Divisor of 399, 197, 905, 949 is 1
