Given numbers are 644, 144, 125, 580

The list of prime factors of all numbers are

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 144 are 2 x 2 x 2 x 2 x 3 x 3

Prime factors of 125 are 5 x 5 x 5

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

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

Given numbers are 644, 144, 125, 580

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

Apply this formula for all numbers.

Step1:

LCM(644, 144) = 23184

GCD(644, 144) = ( 644 x 144 ) / 23184

= 644 / 144

= 644

Step2:

LCM(4, 125) = 500

GCD(4, 125) = ( 4 x 125 ) / 500

= 4 / 125

= 4

Step3:

LCM(1, 580) = 580

GCD(1, 580) = ( 1 x 580 ) / 580

= 1 / 580

= 1

So, Greatest Common Divisor of 644, 144, 125, 580 is 1
