Given numbers are 387, 351, 485, 865

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

Apply this formula for all numbers.

Step1:

LCM(387, 351) = 15093

GCD(387, 351) = ( 387 x 351 ) / 15093

= 387 / 351

= 387

Step2:

LCM(9, 485) = 4365

GCD(9, 485) = ( 9 x 485 ) / 4365

= 9 / 485

= 9

Step3:

LCM(1, 865) = 865

GCD(1, 865) = ( 1 x 865 ) / 865

= 1 / 865

= 1

So, Greatest Common Divisor of 387, 351, 485, 865 is 1
