Given numbers are 493, 646, 665, 345
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(493, 646) = 18734
GCD(493, 646) = ( 493 x 646 ) / 18734
= 493 / 646
= 493
Step2:
LCM(17, 665) = 11305
GCD(17, 665) = ( 17 x 665 ) / 11305
= 17 / 665
= 17
Step3:
LCM(1, 345) = 345
GCD(1, 345) = ( 1 x 345 ) / 345
= 1 / 345
= 1
So, Greatest Common Divisor of 493, 646, 665, 345 is 1
