Given numbers are 309, 771, 153, 899

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

Apply this formula for all numbers.

Step1:

LCM(309, 771) = 79413

GCD(309, 771) = ( 309 x 771 ) / 79413

= 309 / 771

= 309

Step2:

LCM(3, 153) = 153

GCD(3, 153) = ( 3 x 153 ) / 153

= 3 / 153

= 3

Step3:

LCM(3, 899) = 2697

GCD(3, 899) = ( 3 x 899 ) / 2697

= 3 / 899

= 3

So, Greatest Common Divisor of 309, 771, 153, 899 is 1
