Given numbers are 819, 777, 65, 258

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

Apply this formula for all numbers.

Step1:

LCM(819, 777) = 30303

GCD(819, 777) = ( 819 x 777 ) / 30303

= 819 / 777

= 819

Step2:

LCM(21, 65) = 1365

GCD(21, 65) = ( 21 x 65 ) / 1365

= 21 / 65

= 21

Step3:

LCM(1, 258) = 258

GCD(1, 258) = ( 1 x 258 ) / 258

= 1 / 258

= 1

So, Greatest Common Divisor of 819, 777, 65, 258 is 1
