Given numbers are 786, 171, 289, 909

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

Apply this formula for all numbers.

Step1:

LCM(786, 171) = 44802

GCD(786, 171) = ( 786 x 171 ) / 44802

= 786 / 171

= 786

Step2:

LCM(3, 289) = 867

GCD(3, 289) = ( 3 x 289 ) / 867

= 3 / 289

= 3

Step3:

LCM(1, 909) = 909

GCD(1, 909) = ( 1 x 909 ) / 909

= 1 / 909

= 1

So, Greatest Common Divisor of 786, 171, 289, 909 is 1
