Given numbers are 309, 717, 407, 897

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

Apply this formula for all numbers.

Step1:

LCM(309, 717) = 73851

GCD(309, 717) = ( 309 x 717 ) / 73851

= 309 / 717

= 309

Step2:

LCM(3, 407) = 1221

GCD(3, 407) = ( 3 x 407 ) / 1221

= 3 / 407

= 3

Step3:

LCM(1, 897) = 897

GCD(1, 897) = ( 1 x 897 ) / 897

= 1 / 897

= 1

So, Greatest Common Divisor of 309, 717, 407, 897 is 1
