Given numbers are 689, 353, 568, 515
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(689, 353) = 243217
GCD(689, 353) = ( 689 x 353 ) / 243217
= 689 / 353
= 689
Step2:
LCM(1, 568) = 568
GCD(1, 568) = ( 1 x 568 ) / 568
= 1 / 568
= 1
Step3:
LCM(1, 515) = 515
GCD(1, 515) = ( 1 x 515 ) / 515
= 1 / 515
= 1
So, Greatest Common Divisor of 689, 353, 568, 515 is 1
