Given numbers are 819, 364, 855, 216

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

Apply this formula for all numbers.

Step1:

LCM(819, 364) = 3276

GCD(819, 364) = ( 819 x 364 ) / 3276

= 819 / 364

= 819

Step2:

LCM(91, 855) = 77805

GCD(91, 855) = ( 91 x 855 ) / 77805

= 91 / 855

= 91

Step3:

LCM(1, 216) = 216

GCD(1, 216) = ( 1 x 216 ) / 216

= 1 / 216

= 1

So, Greatest Common Divisor of 819, 364, 855, 216 is 1
