Given numbers are 441, 462, 499, 644

The list of prime factors of all numbers are

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

Prime factors of 462 are 2 x 3 x 7 x 11

Prime factors of 499 are 499

Prime factors of 644 are 2 x 2 x 7 x 23

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

Given numbers are 441, 462, 499, 644

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

Apply this formula for all numbers.

Step1:

LCM(441, 462) = 9702

GCD(441, 462) = ( 441 x 462 ) / 9702

= 441 / 462

= 441

Step2:

LCM(21, 499) = 10479

GCD(21, 499) = ( 21 x 499 ) / 10479

= 21 / 499

= 21

Step3:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

So, Greatest Common Divisor of 441, 462, 499, 644 is 1
