Given numbers are 115, 818, 139, 406

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

Apply this formula for all numbers.

Step1:

LCM(115, 818) = 94070

GCD(115, 818) = ( 115 x 818 ) / 94070

= 115 / 818

= 115

Step2:

LCM(1, 139) = 139

GCD(1, 139) = ( 1 x 139 ) / 139

= 1 / 139

= 1

Step3:

LCM(1, 406) = 406

GCD(1, 406) = ( 1 x 406 ) / 406

= 1 / 406

= 1

So, Greatest Common Divisor of 115, 818, 139, 406 is 1
