Given numbers are 721, 221, 742, 693

The list of prime factors of all numbers are

Prime factors of 721 are 7 x 103

Prime factors of 221 are 13 x 17

Prime factors of 742 are 2 x 7 x 53

Prime factors of 693 are 3 x 3 x 7 x 11

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

Given numbers are 721, 221, 742, 693

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

Apply this formula for all numbers.

Step1:

LCM(721, 221) = 159341

GCD(721, 221) = ( 721 x 221 ) / 159341

= 721 / 221

= 721

Step2:

LCM(1, 742) = 742

GCD(1, 742) = ( 1 x 742 ) / 742

= 1 / 742

= 1

Step3:

LCM(1, 693) = 693

GCD(1, 693) = ( 1 x 693 ) / 693

= 1 / 693

= 1

So, Greatest Common Divisor of 721, 221, 742, 693 is 1
