Given numbers are 810, 921, 478, 702

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 921 are 3 x 307

Prime factors of 478 are 2 x 239

Prime factors of 702 are 2 x 3 x 3 x 3 x 13

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

Given numbers are 810, 921, 478, 702

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

Apply this formula for all numbers.

Step1:

LCM(810, 921) = 248670

GCD(810, 921) = ( 810 x 921 ) / 248670

= 810 / 921

= 810

Step2:

LCM(3, 478) = 1434

GCD(3, 478) = ( 3 x 478 ) / 1434

= 3 / 478

= 3

Step3:

LCM(1, 702) = 702

GCD(1, 702) = ( 1 x 702 ) / 702

= 1 / 702

= 1

So, Greatest Common Divisor of 810, 921, 478, 702 is 1
