Given numbers are 305, 555, 489, 890
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(305, 555) = 33855
GCD(305, 555) = ( 305 x 555 ) / 33855
= 305 / 555
= 305
Step2:
LCM(5, 489) = 2445
GCD(5, 489) = ( 5 x 489 ) / 2445
= 5 / 489
= 5
Step3:
LCM(1, 890) = 890
GCD(1, 890) = ( 1 x 890 ) / 890
= 1 / 890
= 1
So, Greatest Common Divisor of 305, 555, 489, 890 is 1
