The list of prime factors of all numbers are
Prime factors of 580 are 2 x 2 x 5 x 29
Prime factors of 205 are 5 x 41
Prime factors of 407 are 11 x 37
Prime factors of 420 are 2 x 2 x 3 x 5 x 7
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 580, 205, 407, 420
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(580, 205) = 23780
GCD(580, 205) = ( 580 x 205 ) / 23780
= 580 / 205
= 580
Step2:
LCM(5, 407) = 2035
GCD(5, 407) = ( 5 x 407 ) / 2035
= 5 / 407
= 5
Step3:
LCM(1, 420) = 420
GCD(1, 420) = ( 1 x 420 ) / 420
= 1 / 420
= 1
So, Greatest Common Divisor of 580, 205, 407, 420 is 1
