Given numbers are 755, 644, 209, 500

The list of prime factors of all numbers are

Prime factors of 755 are 5 x 151

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

Prime factors of 209 are 11 x 19

Prime factors of 500 are 2 x 2 x 5 x 5 x 5

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

Given numbers are 755, 644, 209, 500

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

Apply this formula for all numbers.

Step1:

LCM(755, 644) = 486220

GCD(755, 644) = ( 755 x 644 ) / 486220

= 755 / 644

= 755

Step2:

LCM(1, 209) = 209

GCD(1, 209) = ( 1 x 209 ) / 209

= 1 / 209

= 1

Step3:

LCM(1, 500) = 500

GCD(1, 500) = ( 1 x 500 ) / 500

= 1 / 500

= 1

So, Greatest Common Divisor of 755, 644, 209, 500 is 1
