GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(405, 856) = 346680
GCD(405, 856) = ( 405 x 856 ) / 346680
= 405 / 856
= 405
Step2:
LCM(1, 928) = 928
GCD(1, 928) = ( 1 x 928 ) / 928
= 1 / 928
= 1
Step3:
LCM(1, 873) = 873
GCD(1, 873) = ( 1 x 873 ) / 873
= 1 / 873
= 1
So, Greatest Common Divisor of 405, 856, 928, 873 is 1
