Given numbers are 657, 457, 438

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

Apply this formula for all numbers.

Step1:

LCM(657, 457) = 300249

GCD(657, 457) = ( 657 x 457 ) / 300249

= 657 / 457

= 657

Step2:

LCM(1, 438) = 438

GCD(1, 438) = ( 1 x 438 ) / 438

= 1 / 438

= 1

So, Greatest Common Divisor of 657, 457, 438 is 1
