GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(399, 411) = 54663
GCD(399, 411) = ( 399 x 411 ) / 54663
= 399 / 411
= 399
Step2:
LCM(3, 864) = 864
GCD(3, 864) = ( 3 x 864 ) / 864
= 3 / 864
= 3
Step3:
LCM(3, 297) = 297
GCD(3, 297) = ( 3 x 297 ) / 297
= 3 / 297
= 3
So, Greatest Common Divisor of 399, 411, 864, 297 is 3
