Given numbers are 259, 960, 398, 558
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(259, 960) = 248640
GCD(259, 960) = ( 259 x 960 ) / 248640
= 259 / 960
= 259
Step2:
LCM(1, 398) = 398
GCD(1, 398) = ( 1 x 398 ) / 398
= 1 / 398
= 1
Step3:
LCM(1, 558) = 558
GCD(1, 558) = ( 1 x 558 ) / 558
= 1 / 558
= 1
So, Greatest Common Divisor of 259, 960, 398, 558 is 1
