Given numbers are 457, 321, 30

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

Apply this formula for all numbers.

Step1:

LCM(457, 321) = 146697

GCD(457, 321) = ( 457 x 321 ) / 146697

= 457 / 321

= 457

Step2:

LCM(1, 30) = 30

GCD(1, 30) = ( 1 x 30 ) / 30

= 1 / 30

= 1

So, Greatest Common Divisor of 457, 321, 30 is 1
