Given numbers are 405, 159, 578, 330
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(405, 159) = 21465
GCD(405, 159) = ( 405 x 159 ) / 21465
= 405 / 159
= 405
Step2:
LCM(3, 578) = 1734
GCD(3, 578) = ( 3 x 578 ) / 1734
= 3 / 578
= 3
Step3:
LCM(1, 330) = 330
GCD(1, 330) = ( 1 x 330 ) / 330
= 1 / 330
= 1
So, Greatest Common Divisor of 405, 159, 578, 330 is 1
