Given numbers are 259, 745, 739, 420
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(259, 745) = 192955
GCD(259, 745) = ( 259 x 745 ) / 192955
= 259 / 745
= 259
Step2:
LCM(1, 739) = 739
GCD(1, 739) = ( 1 x 739 ) / 739
= 1 / 739
= 1
Step3:
LCM(1, 420) = 420
GCD(1, 420) = ( 1 x 420 ) / 420
= 1 / 420
= 1
So, Greatest Common Divisor of 259, 745, 739, 420 is 1
