Given numbers are 231, 784, 660, 622

The list of prime factors of all numbers are

Prime factors of 231 are 3 x 7 x 11

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

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 622 are 2 x 311

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

Given numbers are 231, 784, 660, 622

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

Apply this formula for all numbers.

Step1:

LCM(231, 784) = 25872

GCD(231, 784) = ( 231 x 784 ) / 25872

= 231 / 784

= 231

Step2:

LCM(7, 660) = 4620

GCD(7, 660) = ( 7 x 660 ) / 4620

= 7 / 660

= 7

Step3:

LCM(1, 622) = 622

GCD(1, 622) = ( 1 x 622 ) / 622

= 1 / 622

= 1

So, Greatest Common Divisor of 231, 784, 660, 622 is 1
