Given numbers are 335, 247, 139, 390

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

Apply this formula for all numbers.

Step1:

LCM(335, 247) = 82745

GCD(335, 247) = ( 335 x 247 ) / 82745

= 335 / 247

= 335

Step2:

LCM(1, 139) = 139

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

= 1 / 139

= 1

Step3:

LCM(1, 390) = 390

GCD(1, 390) = ( 1 x 390 ) / 390

= 1 / 390

= 1

So, Greatest Common Divisor of 335, 247, 139, 390 is 1
