Given numbers are 721, 755, 725, 187

The list of prime factors of all numbers are

Prime factors of 721 are 7 x 103

Prime factors of 755 are 5 x 151

Prime factors of 725 are 5 x 5 x 29

Prime factors of 187 are 11 x 17

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

Given numbers are 721, 755, 725, 187

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

Apply this formula for all numbers.

Step1:

LCM(721, 755) = 544355

GCD(721, 755) = ( 721 x 755 ) / 544355

= 721 / 755

= 721

Step2:

LCM(1, 725) = 725

GCD(1, 725) = ( 1 x 725 ) / 725

= 1 / 725

= 1

Step3:

LCM(1, 187) = 187

GCD(1, 187) = ( 1 x 187 ) / 187

= 1 / 187

= 1

So, Greatest Common Divisor of 721, 755, 725, 187 is 1
