GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(397, 423) = 167931
GCD(397, 423) = ( 397 x 423 ) / 167931
= 397 / 423
= 397
Step2:
LCM(1, 738) = 738
GCD(1, 738) = ( 1 x 738 ) / 738
= 1 / 738
= 1
Step3:
LCM(1, 389) = 389
GCD(1, 389) = ( 1 x 389 ) / 389
= 1 / 389
= 1
So, Greatest Common Divisor of 397, 423, 738, 389 is 1
