Given numbers are 978, 363, 555, 803

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

Apply this formula for all numbers.

Step1:

LCM(978, 363) = 118338

GCD(978, 363) = ( 978 x 363 ) / 118338

= 978 / 363

= 978

Step2:

LCM(3, 555) = 555

GCD(3, 555) = ( 3 x 555 ) / 555

= 3 / 555

= 3

Step3:

LCM(3, 803) = 2409

GCD(3, 803) = ( 3 x 803 ) / 2409

= 3 / 803

= 3

So, Greatest Common Divisor of 978, 363, 555, 803 is 1
