Prime factors of 445 are 5 x 89
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 720, 589, 781, 445
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(720, 589) = 424080
GCD(720, 589) = ( 720 x 589 ) / 424080
= 720 / 589
= 720
Step2:
LCM(1, 781) = 781
GCD(1, 781) = ( 1 x 781 ) / 781
= 1 / 781
= 1
Step3:
LCM(1, 445) = 445
GCD(1, 445) = ( 1 x 445 ) / 445
= 1 / 445
= 1
So, Greatest Common Divisor of 720, 589, 781, 445 is 1
