Given numbers are 170, 753, 507, 721

The list of prime factors of all numbers are

Prime factors of 170 are 2 x 5 x 17

Prime factors of 753 are 3 x 251

Prime factors of 507 are 3 x 13 x 13

Prime factors of 721 are 7 x 103

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

Given numbers are 170, 753, 507, 721

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

Apply this formula for all numbers.

Step1:

LCM(170, 753) = 128010

GCD(170, 753) = ( 170 x 753 ) / 128010

= 170 / 753

= 170

Step2:

LCM(1, 507) = 507

GCD(1, 507) = ( 1 x 507 ) / 507

= 1 / 507

= 1

Step3:

LCM(1, 721) = 721

GCD(1, 721) = ( 1 x 721 ) / 721

= 1 / 721

= 1

So, Greatest Common Divisor of 170, 753, 507, 721 is 1
