Given numbers are 385, 399, 987, 843

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

Apply this formula for all numbers.

Step1:

LCM(385, 399) = 21945

GCD(385, 399) = ( 385 x 399 ) / 21945

= 385 / 399

= 385

Step2:

LCM(7, 987) = 987

GCD(7, 987) = ( 7 x 987 ) / 987

= 7 / 987

= 7

Step3:

LCM(7, 843) = 5901

GCD(7, 843) = ( 7 x 843 ) / 5901

= 7 / 843

= 7

So, Greatest Common Divisor of 385, 399, 987, 843 is 1
