GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(489, 259) = 126651
GCD(489, 259) = ( 489 x 259 ) / 126651
= 489 / 259
= 489
Step2:
LCM(1, 805) = 805
GCD(1, 805) = ( 1 x 805 ) / 805
= 1 / 805
= 1
Step3:
LCM(1, 740) = 740
GCD(1, 740) = ( 1 x 740 ) / 740
= 1 / 740
= 1
So, Greatest Common Divisor of 489, 259, 805, 740 is 1
