GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(349, 693) = 241857
GCD(349, 693) = ( 349 x 693 ) / 241857
= 349 / 693
= 349
Step2:
LCM(1, 858) = 858
GCD(1, 858) = ( 1 x 858 ) / 858
= 1 / 858
= 1
Step3:
LCM(1, 115) = 115
GCD(1, 115) = ( 1 x 115 ) / 115
= 1 / 115
= 1
So, Greatest Common Divisor of 349, 693, 858, 115 is 1
