Given numbers are 115, 610, 191, 399

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

Apply this formula for all numbers.

Step1:

LCM(115, 610) = 14030

GCD(115, 610) = ( 115 x 610 ) / 14030

= 115 / 610

= 115

Step2:

LCM(5, 191) = 955

GCD(5, 191) = ( 5 x 191 ) / 955

= 5 / 191

= 5

Step3:

LCM(1, 399) = 399

GCD(1, 399) = ( 1 x 399 ) / 399

= 1 / 399

= 1

So, Greatest Common Divisor of 115, 610, 191, 399 is 1
