Given numbers are 400, 545, 580, 623

The list of prime factors of all numbers are

Prime factors of 400 are 2 x 2 x 2 x 2 x 5 x 5

Prime factors of 545 are 5 x 109

Prime factors of 580 are 2 x 2 x 5 x 29

Prime factors of 623 are 7 x 89

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 400, 545, 580, 623

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(400, 545) = 43600

GCD(400, 545) = ( 400 x 545 ) / 43600

= 400 / 545

= 400

Step2:

LCM(5, 580) = 580

GCD(5, 580) = ( 5 x 580 ) / 580

= 5 / 580

= 5

Step3:

LCM(5, 623) = 3115

GCD(5, 623) = ( 5 x 623 ) / 3115

= 5 / 623

= 5

So, Greatest Common Divisor of 400, 545, 580, 623 is 1
