Given numbers are 386, 662, 305, 915

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

Apply this formula for all numbers.

Step1:

LCM(386, 662) = 127766

GCD(386, 662) = ( 386 x 662 ) / 127766

= 386 / 662

= 386

Step2:

LCM(2, 305) = 610

GCD(2, 305) = ( 2 x 305 ) / 610

= 2 / 305

= 2

Step3:

LCM(1, 915) = 915

GCD(1, 915) = ( 1 x 915 ) / 915

= 1 / 915

= 1

So, Greatest Common Divisor of 386, 662, 305, 915 is 1
