GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(821, 199) = 163379
GCD(821, 199) = ( 821 x 199 ) / 163379
= 821 / 199
= 821
Step2:
LCM(1, 327) = 327
GCD(1, 327) = ( 1 x 327 ) / 327
= 1 / 327
= 1
Step3:
LCM(1, 197) = 197
GCD(1, 197) = ( 1 x 197 ) / 197
= 1 / 197
= 1
So, Greatest Common Divisor of 821, 199, 327, 197 is 1
