Given numbers are 624, 421, 81, 441

The list of prime factors of all numbers are

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

Prime factors of 421 are 421

Prime factors of 81 are 3 x 3 x 3 x 3

Prime factors of 441 are 3 x 3 x 7 x 7

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

Given numbers are 624, 421, 81, 441

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

Apply this formula for all numbers.

Step1:

LCM(624, 421) = 262704

GCD(624, 421) = ( 624 x 421 ) / 262704

= 624 / 421

= 624

Step2:

LCM(1, 81) = 81

GCD(1, 81) = ( 1 x 81 ) / 81

= 1 / 81

= 1

Step3:

LCM(1, 441) = 441

GCD(1, 441) = ( 1 x 441 ) / 441

= 1 / 441

= 1

So, Greatest Common Divisor of 624, 421, 81, 441 is 1
