Given numbers are 420, 550, 726, 447

The list of prime factors of all numbers are

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 550 are 2 x 5 x 5 x 11

Prime factors of 726 are 2 x 3 x 11 x 11

Prime factors of 447 are 3 x 149

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

Given numbers are 420, 550, 726, 447

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

Apply this formula for all numbers.

Step1:

LCM(420, 550) = 23100

GCD(420, 550) = ( 420 x 550 ) / 23100

= 420 / 550

= 420

Step2:

LCM(10, 726) = 3630

GCD(10, 726) = ( 10 x 726 ) / 3630

= 10 / 726

= 10

Step3:

LCM(2, 447) = 894

GCD(2, 447) = ( 2 x 447 ) / 894

= 2 / 447

= 2

So, Greatest Common Divisor of 420, 550, 726, 447 is 1
