Given numbers are 489, 351, 417, 187
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(489, 351) = 57213
GCD(489, 351) = ( 489 x 351 ) / 57213
= 489 / 351
= 489
Step2:
LCM(3, 417) = 417
GCD(3, 417) = ( 3 x 417 ) / 417
= 3 / 417
= 3
Step3:
LCM(3, 187) = 561
GCD(3, 187) = ( 3 x 187 ) / 561
= 3 / 187
= 3
So, Greatest Common Divisor of 489, 351, 417, 187 is 1
