Given numbers are 277, 440, 136, 489
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(277, 440) = 121880
GCD(277, 440) = ( 277 x 440 ) / 121880
= 277 / 440
= 277
Step2:
LCM(1, 136) = 136
GCD(1, 136) = ( 1 x 136 ) / 136
= 1 / 136
= 1
Step3:
LCM(1, 489) = 489
GCD(1, 489) = ( 1 x 489 ) / 489
= 1 / 489
= 1
So, Greatest Common Divisor of 277, 440, 136, 489 is 1
