GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(349, 823) = 287227
GCD(349, 823) = ( 349 x 823 ) / 287227
= 349 / 823
= 349
Step2:
LCM(1, 685) = 685
GCD(1, 685) = ( 1 x 685 ) / 685
= 1 / 685
= 1
Step3:
LCM(1, 689) = 689
GCD(1, 689) = ( 1 x 689 ) / 689
= 1 / 689
= 1
So, Greatest Common Divisor of 349, 823, 685, 689 is 1
