Given numbers are 357, 785, 309

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

Apply this formula for all numbers.

Step1:

LCM(357, 785) = 280245

GCD(357, 785) = ( 357 x 785 ) / 280245

= 357 / 785

= 357

Step2:

LCM(1, 309) = 309

GCD(1, 309) = ( 1 x 309 ) / 309

= 1 / 309

= 1

So, Greatest Common Divisor of 357, 785, 309 is 1
