Given numbers are 724, 755, 657, 687

The list of prime factors of all numbers are

Prime factors of 724 are 2 x 2 x 181

Prime factors of 755 are 5 x 151

Prime factors of 657 are 3 x 3 x 73

Prime factors of 687 are 3 x 229

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

Given numbers are 724, 755, 657, 687

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

Apply this formula for all numbers.

Step1:

LCM(724, 755) = 546620

GCD(724, 755) = ( 724 x 755 ) / 546620

= 724 / 755

= 724

Step2:

LCM(1, 657) = 657

GCD(1, 657) = ( 1 x 657 ) / 657

= 1 / 657

= 1

Step3:

LCM(1, 687) = 687

GCD(1, 687) = ( 1 x 687 ) / 687

= 1 / 687

= 1

So, Greatest Common Divisor of 724, 755, 657, 687 is 1
