Given numbers are 909, 207, 730, 691

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

Apply this formula for all numbers.

Step1:

LCM(909, 207) = 20907

GCD(909, 207) = ( 909 x 207 ) / 20907

= 909 / 207

= 909

Step2:

LCM(9, 730) = 6570

GCD(9, 730) = ( 9 x 730 ) / 6570

= 9 / 730

= 9

Step3:

LCM(1, 691) = 691

GCD(1, 691) = ( 1 x 691 ) / 691

= 1 / 691

= 1

So, Greatest Common Divisor of 909, 207, 730, 691 is 1
