Given numbers are 393, 854, 721, 817
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(393, 854) = 335622
GCD(393, 854) = ( 393 x 854 ) / 335622
= 393 / 854
= 393
Step2:
LCM(1, 721) = 721
GCD(1, 721) = ( 1 x 721 ) / 721
= 1 / 721
= 1
Step3:
LCM(1, 817) = 817
GCD(1, 817) = ( 1 x 817 ) / 817
= 1 / 817
= 1
So, Greatest Common Divisor of 393, 854, 721, 817 is 1
