Given numbers are 217, 493, 403, 289
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(217, 493) = 106981
GCD(217, 493) = ( 217 x 493 ) / 106981
= 217 / 493
= 217
Step2:
LCM(1, 403) = 403
GCD(1, 403) = ( 1 x 403 ) / 403
= 1 / 403
= 1
Step3:
LCM(1, 289) = 289
GCD(1, 289) = ( 1 x 289 ) / 289
= 1 / 289
= 1
So, Greatest Common Divisor of 217, 493, 403, 289 is 1
