Given numbers are 873, 855, 687, 343
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(873, 855) = 82935
GCD(873, 855) = ( 873 x 855 ) / 82935
= 873 / 855
= 873
Step2:
LCM(9, 687) = 2061
GCD(9, 687) = ( 9 x 687 ) / 2061
= 9 / 687
= 9
Step3:
LCM(3, 343) = 1029
GCD(3, 343) = ( 3 x 343 ) / 1029
= 3 / 343
= 3
So, Greatest Common Divisor of 873, 855, 687, 343 is 1
