GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(221, 349) = 77129
GCD(221, 349) = ( 221 x 349 ) / 77129
= 221 / 349
= 221
Step2:
LCM(1, 994) = 994
GCD(1, 994) = ( 1 x 994 ) / 994
= 1 / 994
= 1
Step3:
LCM(1, 380) = 380
GCD(1, 380) = ( 1 x 380 ) / 380
= 1 / 380
= 1
So, Greatest Common Divisor of 221, 349, 994, 380 is 1
