Given numbers are 819, 585, 245, 540

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

Apply this formula for all numbers.

Step1:

LCM(819, 585) = 4095

GCD(819, 585) = ( 819 x 585 ) / 4095

= 819 / 585

= 819

Step2:

LCM(117, 245) = 28665

GCD(117, 245) = ( 117 x 245 ) / 28665

= 117 / 245

= 117

Step3:

LCM(1, 540) = 540

GCD(1, 540) = ( 1 x 540 ) / 540

= 1 / 540

= 1

So, Greatest Common Divisor of 819, 585, 245, 540 is 1
