Given numbers are 843, 138, 47

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

Apply this formula for all numbers.

Step1:

LCM(843, 138) = 38778

GCD(843, 138) = ( 843 x 138 ) / 38778

= 843 / 138

= 843

Step2:

LCM(3, 47) = 141

GCD(3, 47) = ( 3 x 47 ) / 141

= 3 / 47

= 3

So, Greatest Common Divisor of 843, 138, 47 is 1
