Given numbers are 646, 285, 675, 385

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

Apply this formula for all numbers.

Step1:

LCM(646, 285) = 9690

GCD(646, 285) = ( 646 x 285 ) / 9690

= 646 / 285

= 646

Step2:

LCM(19, 675) = 12825

GCD(19, 675) = ( 19 x 675 ) / 12825

= 19 / 675

= 19

Step3:

LCM(1, 385) = 385

GCD(1, 385) = ( 1 x 385 ) / 385

= 1 / 385

= 1

So, Greatest Common Divisor of 646, 285, 675, 385 is 1
