Given numbers are 646, 823, 295, 485

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

Apply this formula for all numbers.

Step1:

LCM(646, 823) = 531658

GCD(646, 823) = ( 646 x 823 ) / 531658

= 646 / 823

= 646

Step2:

LCM(1, 295) = 295

GCD(1, 295) = ( 1 x 295 ) / 295

= 1 / 295

= 1

Step3:

LCM(1, 485) = 485

GCD(1, 485) = ( 1 x 485 ) / 485

= 1 / 485

= 1

So, Greatest Common Divisor of 646, 823, 295, 485 is 1
