Given numbers are 646, 831, 406, 759

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

Apply this formula for all numbers.

Step1:

LCM(646, 831) = 536826

GCD(646, 831) = ( 646 x 831 ) / 536826

= 646 / 831

= 646

Step2:

LCM(1, 406) = 406

GCD(1, 406) = ( 1 x 406 ) / 406

= 1 / 406

= 1

Step3:

LCM(1, 759) = 759

GCD(1, 759) = ( 1 x 759 ) / 759

= 1 / 759

= 1

So, Greatest Common Divisor of 646, 831, 406, 759 is 1
