Given numbers are 918, 816, 206, 489
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(918, 816) = 7344
GCD(918, 816) = ( 918 x 816 ) / 7344
= 918 / 816
= 918
Step2:
LCM(102, 206) = 10506
GCD(102, 206) = ( 102 x 206 ) / 10506
= 102 / 206
= 102
Step3:
LCM(2, 489) = 978
GCD(2, 489) = ( 2 x 489 ) / 978
= 2 / 489
= 2
So, Greatest Common Divisor of 918, 816, 206, 489 is 1
