Given numbers are 139, 168, 327, 646

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

Apply this formula for all numbers.

Step1:

LCM(139, 168) = 23352

GCD(139, 168) = ( 139 x 168 ) / 23352

= 139 / 168

= 139

Step2:

LCM(1, 327) = 327

GCD(1, 327) = ( 1 x 327 ) / 327

= 1 / 327

= 1

Step3:

LCM(1, 646) = 646

GCD(1, 646) = ( 1 x 646 ) / 646

= 1 / 646

= 1

So, Greatest Common Divisor of 139, 168, 327, 646 is 1
