Given numbers are 399, 168, 818, 831
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(399, 168) = 3192
GCD(399, 168) = ( 399 x 168 ) / 3192
= 399 / 168
= 399
Step2:
LCM(21, 818) = 17178
GCD(21, 818) = ( 21 x 818 ) / 17178
= 21 / 818
= 21
Step3:
LCM(1, 831) = 831
GCD(1, 831) = ( 1 x 831 ) / 831
= 1 / 831
= 1
So, Greatest Common Divisor of 399, 168, 818, 831 is 1
