GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(221, 939) = 207519
GCD(221, 939) = ( 221 x 939 ) / 207519
= 221 / 939
= 221
Step2:
LCM(1, 249) = 249
GCD(1, 249) = ( 1 x 249 ) / 249
= 1 / 249
= 1
Step3:
LCM(1, 384) = 384
GCD(1, 384) = ( 1 x 384 ) / 384
= 1 / 384
= 1
So, Greatest Common Divisor of 221, 939, 249, 384 is 1
