Given numbers are 259, 707, 345, 489
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(259, 707) = 26159
GCD(259, 707) = ( 259 x 707 ) / 26159
= 259 / 707
= 259
Step2:
LCM(7, 345) = 2415
GCD(7, 345) = ( 7 x 345 ) / 2415
= 7 / 345
= 7
Step3:
LCM(1, 489) = 489
GCD(1, 489) = ( 1 x 489 ) / 489
= 1 / 489
= 1
So, Greatest Common Divisor of 259, 707, 345, 489 is 1
