Given numbers are 407, 284, 657

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

Apply this formula for all numbers.

Step1:

LCM(407, 284) = 115588

GCD(407, 284) = ( 407 x 284 ) / 115588

= 407 / 284

= 407

Step2:

LCM(1, 657) = 657

GCD(1, 657) = ( 1 x 657 ) / 657

= 1 / 657

= 1

So, Greatest Common Divisor of 407, 284, 657 is 1
