Given numbers are 646, 949, 314, 805

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

Apply this formula for all numbers.

Step1:

LCM(646, 949) = 613054

GCD(646, 949) = ( 646 x 949 ) / 613054

= 646 / 949

= 646

Step2:

LCM(1, 314) = 314

GCD(1, 314) = ( 1 x 314 ) / 314

= 1 / 314

= 1

Step3:

LCM(1, 805) = 805

GCD(1, 805) = ( 1 x 805 ) / 805

= 1 / 805

= 1

So, Greatest Common Divisor of 646, 949, 314, 805 is 1
