Given numbers are 309, 903, 706, 139

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

Apply this formula for all numbers.

Step1:

LCM(309, 903) = 93009

GCD(309, 903) = ( 309 x 903 ) / 93009

= 309 / 903

= 309

Step2:

LCM(3, 706) = 2118

GCD(3, 706) = ( 3 x 706 ) / 2118

= 3 / 706

= 3

Step3:

LCM(1, 139) = 139

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

= 1 / 139

= 1

So, Greatest Common Divisor of 309, 903, 706, 139 is 1
