Given numbers are 315, 273, 821, 783

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

Apply this formula for all numbers.

Step1:

LCM(315, 273) = 4095

GCD(315, 273) = ( 315 x 273 ) / 4095

= 315 / 273

= 315

Step2:

LCM(21, 821) = 17241

GCD(21, 821) = ( 21 x 821 ) / 17241

= 21 / 821

= 21

Step3:

LCM(1, 783) = 783

GCD(1, 783) = ( 1 x 783 ) / 783

= 1 / 783

= 1

So, Greatest Common Divisor of 315, 273, 821, 783 is 1
