Given numbers are 406, 427, 489, 287
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(406, 427) = 24766
GCD(406, 427) = ( 406 x 427 ) / 24766
= 406 / 427
= 406
Step2:
LCM(7, 489) = 3423
GCD(7, 489) = ( 7 x 489 ) / 3423
= 7 / 489
= 7
Step3:
LCM(1, 287) = 287
GCD(1, 287) = ( 1 x 287 ) / 287
= 1 / 287
= 1
So, Greatest Common Divisor of 406, 427, 489, 287 is 1
