Given numbers are 428, 440, 879, 450

The list of prime factors of all numbers are

Prime factors of 428 are 2 x 2 x 107

Prime factors of 440 are 2 x 2 x 2 x 5 x 11

Prime factors of 879 are 3 x 293

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

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

Given numbers are 428, 440, 879, 450

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

Apply this formula for all numbers.

Step1:

LCM(428, 440) = 47080

GCD(428, 440) = ( 428 x 440 ) / 47080

= 428 / 440

= 428

Step2:

LCM(4, 879) = 3516

GCD(4, 879) = ( 4 x 879 ) / 3516

= 4 / 879

= 4

Step3:

LCM(1, 450) = 450

GCD(1, 450) = ( 1 x 450 ) / 450

= 1 / 450

= 1

So, Greatest Common Divisor of 428, 440, 879, 450 is 1
