The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 915, 540, 342, 389

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

Apply this formula for all numbers.

Step1:

LCM(915, 540) = 32940

GCD(915, 540) = ( 915 x 540 ) / 32940

= 915 / 540

= 915

Step2:

LCM(15, 342) = 1710

GCD(15, 342) = ( 15 x 342 ) / 1710

= 15 / 342

= 15

Step3:

LCM(3, 389) = 1167

GCD(3, 389) = ( 3 x 389 ) / 1167

= 3 / 389

= 3

So, Greatest Common Divisor of 915, 540, 342, 389 is 1
