Given numbers are 386, 105, 428

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

Apply this formula for all numbers.

Step1:

LCM(386, 105) = 40530

GCD(386, 105) = ( 386 x 105 ) / 40530

= 386 / 105

= 386

Step2:

LCM(1, 428) = 428

GCD(1, 428) = ( 1 x 428 ) / 428

= 1 / 428

= 1

So, Greatest Common Divisor of 386, 105, 428 is 1
