Given numbers are 813, 564, 668, 784

The list of prime factors of all numbers are

Prime factors of 813 are 3 x 271

Prime factors of 564 are 2 x 2 x 3 x 47

Prime factors of 668 are 2 x 2 x 167

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

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

Given numbers are 813, 564, 668, 784

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

Apply this formula for all numbers.

Step1:

LCM(813, 564) = 152844

GCD(813, 564) = ( 813 x 564 ) / 152844

= 813 / 564

= 813

Step2:

LCM(3, 668) = 2004

GCD(3, 668) = ( 3 x 668 ) / 2004

= 3 / 668

= 3

Step3:

LCM(1, 784) = 784

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

= 1 / 784

= 1

So, Greatest Common Divisor of 813, 564, 668, 784 is 1
