GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(697, 847) = 590359
GCD(697, 847) = ( 697 x 847 ) / 590359
= 697 / 847
= 697
Step2:
LCM(1, 405) = 405
GCD(1, 405) = ( 1 x 405 ) / 405
= 1 / 405
= 1
Step3:
LCM(1, 329) = 329
GCD(1, 329) = ( 1 x 329 ) / 329
= 1 / 329
= 1
So, Greatest Common Divisor of 697, 847, 405, 329 is 1
