Given numbers are 235, 645, 784, 721

The list of prime factors of all numbers are

Prime factors of 235 are 5 x 47

Prime factors of 645 are 3 x 5 x 43

Prime factors of 784 are 2 x 2 x 2 x 2 x 7 x 7

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 235, 645, 784, 721

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

Apply this formula for all numbers.

Step1:

LCM(235, 645) = 30315

GCD(235, 645) = ( 235 x 645 ) / 30315

= 235 / 645

= 235

Step2:

LCM(5, 784) = 3920

GCD(5, 784) = ( 5 x 784 ) / 3920

= 5 / 784

= 5

Step3:

LCM(1, 721) = 721

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

= 1 / 721

= 1

So, Greatest Common Divisor of 235, 645, 784, 721 is 1
