Given numbers are 105, 399, 473, 391
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(105, 399) = 1995
GCD(105, 399) = ( 105 x 399 ) / 1995
= 105 / 399
= 105
Step2:
LCM(21, 473) = 9933
GCD(21, 473) = ( 21 x 473 ) / 9933
= 21 / 473
= 21
Step3:
LCM(1, 391) = 391
GCD(1, 391) = ( 1 x 391 ) / 391
= 1 / 391
= 1
So, Greatest Common Divisor of 105, 399, 473, 391 is 1
