Given numbers are 207, 609, 909, 617

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

Apply this formula for all numbers.

Step1:

LCM(207, 609) = 42021

GCD(207, 609) = ( 207 x 609 ) / 42021

= 207 / 609

= 207

Step2:

LCM(3, 909) = 909

GCD(3, 909) = ( 3 x 909 ) / 909

= 3 / 909

= 3

Step3:

LCM(3, 617) = 1851

GCD(3, 617) = ( 3 x 617 ) / 1851

= 3 / 617

= 3

So, Greatest Common Divisor of 207, 609, 909, 617 is 1
