Given numbers are 393, 991, 982, 663
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(393, 991) = 389463
GCD(393, 991) = ( 393 x 991 ) / 389463
= 393 / 991
= 393
Step2:
LCM(1, 982) = 982
GCD(1, 982) = ( 1 x 982 ) / 982
= 1 / 982
= 1
Step3:
LCM(1, 663) = 663
GCD(1, 663) = ( 1 x 663 ) / 663
= 1 / 663
= 1
So, Greatest Common Divisor of 393, 991, 982, 663 is 1
