The list of prime factors of all numbers are
Prime factors of 305 are 5 x 61
Prime factors of 780 are 2 x 2 x 3 x 5 x 13
Prime factors of 845 are 5 x 13 x 13
Prime factors of 606 are 2 x 3 x 101
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 305, 780, 845, 606
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(305, 780) = 47580
GCD(305, 780) = ( 305 x 780 ) / 47580
= 305 / 780
= 305
Step2:
LCM(5, 845) = 845
GCD(5, 845) = ( 5 x 845 ) / 845
= 5 / 845
= 5
Step3:
LCM(5, 606) = 3030
GCD(5, 606) = ( 5 x 606 ) / 3030
= 5 / 606
= 5
So, Greatest Common Divisor of 305, 780, 845, 606 is 1
