Given numbers are 441, 407, 55, 312

The list of prime factors of all numbers are

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

Prime factors of 407 are 11 x 37

Prime factors of 55 are 5 x 11

Prime factors of 312 are 2 x 2 x 2 x 3 x 13

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

Given numbers are 441, 407, 55, 312

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

Apply this formula for all numbers.

Step1:

LCM(441, 407) = 179487

GCD(441, 407) = ( 441 x 407 ) / 179487

= 441 / 407

= 441

Step2:

LCM(1, 55) = 55

GCD(1, 55) = ( 1 x 55 ) / 55

= 1 / 55

= 1

Step3:

LCM(1, 312) = 312

GCD(1, 312) = ( 1 x 312 ) / 312

= 1 / 312

= 1

So, Greatest Common Divisor of 441, 407, 55, 312 is 1
