Given numbers are 810, 455, 244, 784

The list of prime factors of all numbers are

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

Prime factors of 455 are 5 x 7 x 13

Prime factors of 244 are 2 x 2 x 61

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 810, 455, 244, 784

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

Apply this formula for all numbers.

Step1:

LCM(810, 455) = 73710

GCD(810, 455) = ( 810 x 455 ) / 73710

= 810 / 455

= 810

Step2:

LCM(5, 244) = 1220

GCD(5, 244) = ( 5 x 244 ) / 1220

= 5 / 244

= 5

Step3:

LCM(1, 784) = 784

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

= 1 / 784

= 1

So, Greatest Common Divisor of 810, 455, 244, 784 is 1
