Given numbers are 405, 351, 978, 797

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

Apply this formula for all numbers.

Step1:

LCM(405, 351) = 5265

GCD(405, 351) = ( 405 x 351 ) / 5265

= 405 / 351

= 405

Step2:

LCM(27, 978) = 8802

GCD(27, 978) = ( 27 x 978 ) / 8802

= 27 / 978

= 27

Step3:

LCM(3, 797) = 2391

GCD(3, 797) = ( 3 x 797 ) / 2391

= 3 / 797

= 3

So, Greatest Common Divisor of 405, 351, 978, 797 is 1
