Given numbers are 297, 143, 624, 810

The list of prime factors of all numbers are

Prime factors of 297 are 3 x 3 x 3 x 11

Prime factors of 143 are 11 x 13

Prime factors of 624 are 2 x 2 x 2 x 2 x 3 x 13

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 297, 143, 624, 810

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

Apply this formula for all numbers.

Step1:

LCM(297, 143) = 3861

GCD(297, 143) = ( 297 x 143 ) / 3861

= 297 / 143

= 297

Step2:

LCM(11, 624) = 6864

GCD(11, 624) = ( 11 x 624 ) / 6864

= 11 / 624

= 11

Step3:

LCM(1, 810) = 810

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

= 1 / 810

= 1

So, Greatest Common Divisor of 297, 143, 624, 810 is 1
