Given numbers are 385, 195, 914, 643

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

Apply this formula for all numbers.

Step1:

LCM(385, 195) = 15015

GCD(385, 195) = ( 385 x 195 ) / 15015

= 385 / 195

= 385

Step2:

LCM(5, 914) = 4570

GCD(5, 914) = ( 5 x 914 ) / 4570

= 5 / 914

= 5

Step3:

LCM(1, 643) = 643

GCD(1, 643) = ( 1 x 643 ) / 643

= 1 / 643

= 1

So, Greatest Common Divisor of 385, 195, 914, 643 is 1
