Given numbers are 843, 210, 407, 406
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(843, 210) = 59010
GCD(843, 210) = ( 843 x 210 ) / 59010
= 843 / 210
= 843
Step2:
LCM(3, 407) = 1221
GCD(3, 407) = ( 3 x 407 ) / 1221
= 3 / 407
= 3
Step3:
LCM(1, 406) = 406
GCD(1, 406) = ( 1 x 406 ) / 406
= 1 / 406
= 1
So, Greatest Common Divisor of 843, 210, 407, 406 is 1
