Given numbers are 821, 198, 193, 363

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

Apply this formula for all numbers.

Step1:

LCM(821, 198) = 162558

GCD(821, 198) = ( 821 x 198 ) / 162558

= 821 / 198

= 821

Step2:

LCM(1, 193) = 193

GCD(1, 193) = ( 1 x 193 ) / 193

= 1 / 193

= 1

Step3:

LCM(1, 363) = 363

GCD(1, 363) = ( 1 x 363 ) / 363

= 1 / 363

= 1

So, Greatest Common Divisor of 821, 198, 193, 363 is 1
