Find GCD of 580, 205, 407, 420 using Prime Factorization

Given numbers are 580, 205, 407, 420

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

Steps to Calculate GCD of 580, 205, 407, 420 using LCM Formula

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
