GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(189, 991) = 187299
GCD(189, 991) = ( 189 x 991 ) / 187299
= 189 / 991
= 189
Step2:
LCM(1, 621) = 621
GCD(1, 621) = ( 1 x 621 ) / 621
= 1 / 621
= 1
Step3:
LCM(1, 242) = 242
GCD(1, 242) = ( 1 x 242 ) / 242
= 1 / 242
= 1
So, Greatest Common Divisor of 189, 991, 621, 242 is 1
