Prime factors of 515 are 5 x 103
Prime factors of 386 are 2 x 193
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 205, 330, 515, 386
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(205, 330) = 13530
GCD(205, 330) = ( 205 x 330 ) / 13530
= 205 / 330
= 205
Step2:
LCM(5, 515) = 515
GCD(5, 515) = ( 5 x 515 ) / 515
= 5 / 515
= 5
Step3:
LCM(5, 386) = 1930
GCD(5, 386) = ( 5 x 386 ) / 1930
= 5 / 386
= 5
So, Greatest Common Divisor of 205, 330, 515, 386 is 1
