Given numbers are 870, 397, 450, 457

The list of prime factors of all numbers are

Prime factors of 870 are 2 x 3 x 5 x 29

Prime factors of 397 are 397

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

Prime factors of 457 are 457

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

Given numbers are 870, 397, 450, 457

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

Apply this formula for all numbers.

Step1:

LCM(870, 397) = 345390

GCD(870, 397) = ( 870 x 397 ) / 345390

= 870 / 397

= 870

Step2:

LCM(1, 450) = 450

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

= 1 / 450

= 1

Step3:

LCM(1, 457) = 457

GCD(1, 457) = ( 1 x 457 ) / 457

= 1 / 457

= 1

So, Greatest Common Divisor of 870, 397, 450, 457 is 1
