Given numbers are 390, 989, 385, 379

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

Apply this formula for all numbers.

Step1:

LCM(390, 989) = 385710

GCD(390, 989) = ( 390 x 989 ) / 385710

= 390 / 989

= 390

Step2:

LCM(1, 385) = 385

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

= 1 / 385

= 1

Step3:

LCM(1, 379) = 379

GCD(1, 379) = ( 1 x 379 ) / 379

= 1 / 379

= 1

So, Greatest Common Divisor of 390, 989, 385, 379 is 1
