Given numbers are 890, 665, 789, 385

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

Apply this formula for all numbers.

Step1:

LCM(890, 665) = 118370

GCD(890, 665) = ( 890 x 665 ) / 118370

= 890 / 665

= 890

Step2:

LCM(5, 789) = 3945

GCD(5, 789) = ( 5 x 789 ) / 3945

= 5 / 789

= 5

Step3:

LCM(1, 385) = 385

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

= 1 / 385

= 1

So, Greatest Common Divisor of 890, 665, 789, 385 is 1
