Given numbers are 813, 139, 208

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

Apply this formula for all numbers.

Step1:

LCM(813, 139) = 113007

GCD(813, 139) = ( 813 x 139 ) / 113007

= 813 / 139

= 813

Step2:

LCM(1, 208) = 208

GCD(1, 208) = ( 1 x 208 ) / 208

= 1 / 208

= 1

So, Greatest Common Divisor of 813, 139, 208 is 1
