Given numbers are 450, 420, 611, 249

The list of prime factors of all numbers are

Prime factors of 450 are 2 x 3 x 3 x 5 x 5

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

Prime factors of 611 are 13 x 47

Prime factors of 249 are 3 x 83

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

Given numbers are 450, 420, 611, 249

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

Apply this formula for all numbers.

Step1:

LCM(450, 420) = 6300

GCD(450, 420) = ( 450 x 420 ) / 6300

= 450 / 420

= 450

Step2:

LCM(30, 611) = 18330

GCD(30, 611) = ( 30 x 611 ) / 18330

= 30 / 611

= 30

Step3:

LCM(1, 249) = 249

GCD(1, 249) = ( 1 x 249 ) / 249

= 1 / 249

= 1

So, Greatest Common Divisor of 450, 420, 611, 249 is 1
