Given numbers are 668, 521, 784, 810

The list of prime factors of all numbers are

Prime factors of 668 are 2 x 2 x 167

Prime factors of 521 are 521

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

Prime factors of 810 are 2 x 3 x 3 x 3 x 3 x 5

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

Given numbers are 668, 521, 784, 810

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

Apply this formula for all numbers.

Step1:

LCM(668, 521) = 348028

GCD(668, 521) = ( 668 x 521 ) / 348028

= 668 / 521

= 668

Step2:

LCM(1, 784) = 784

GCD(1, 784) = ( 1 x 784 ) / 784

= 1 / 784

= 1

Step3:

LCM(1, 810) = 810

GCD(1, 810) = ( 1 x 810 ) / 810

= 1 / 810

= 1

So, Greatest Common Divisor of 668, 521, 784, 810 is 1
