Given numbers are 489, 511, 859, 291
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(489, 511) = 249879
GCD(489, 511) = ( 489 x 511 ) / 249879
= 489 / 511
= 489
Step2:
LCM(1, 859) = 859
GCD(1, 859) = ( 1 x 859 ) / 859
= 1 / 859
= 1
Step3:
LCM(1, 291) = 291
GCD(1, 291) = ( 1 x 291 ) / 291
= 1 / 291
= 1
So, Greatest Common Divisor of 489, 511, 859, 291 is 1
