Given numbers are 280, 397, 543, 432

The list of prime factors of all numbers are

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

Prime factors of 397 are 397

Prime factors of 543 are 3 x 181

Prime factors of 432 are 2 x 2 x 2 x 2 x 3 x 3 x 3

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

Given numbers are 280, 397, 543, 432

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

Apply this formula for all numbers.

Step1:

LCM(280, 397) = 111160

GCD(280, 397) = ( 280 x 397 ) / 111160

= 280 / 397

= 280

Step2:

LCM(1, 543) = 543

GCD(1, 543) = ( 1 x 543 ) / 543

= 1 / 543

= 1

Step3:

LCM(1, 432) = 432

GCD(1, 432) = ( 1 x 432 ) / 432

= 1 / 432

= 1

So, Greatest Common Divisor of 280, 397, 543, 432 is 1
