GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(321, 864) = 92448
GCD(321, 864) = ( 321 x 864 ) / 92448
= 321 / 864
= 321
Step2:
LCM(3, 399) = 399
GCD(3, 399) = ( 3 x 399 ) / 399
= 3 / 399
= 3
Step3:
LCM(3, 423) = 423
GCD(3, 423) = ( 3 x 423 ) / 423
= 3 / 423
= 3
So, Greatest Common Divisor of 321, 864, 399, 423 is 3
