Given numbers are 133, 128, 280, 814

The list of prime factors of all numbers are

Prime factors of 133 are 7 x 19

Prime factors of 128 are 2 x 2 x 2 x 2 x 2 x 2 x 2

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

Prime factors of 814 are 2 x 11 x 37

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

Given numbers are 133, 128, 280, 814

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

Apply this formula for all numbers.

Step1:

LCM(133, 128) = 17024

GCD(133, 128) = ( 133 x 128 ) / 17024

= 133 / 128

= 133

Step2:

LCM(1, 280) = 280

GCD(1, 280) = ( 1 x 280 ) / 280

= 1 / 280

= 1

Step3:

LCM(1, 814) = 814

GCD(1, 814) = ( 1 x 814 ) / 814

= 1 / 814

= 1

So, Greatest Common Divisor of 133, 128, 280, 814 is 1
