Given numbers are 383, 130, 455, 280

The list of prime factors of all numbers are

Prime factors of 383 are 383

Prime factors of 130 are 2 x 5 x 13

Prime factors of 455 are 5 x 7 x 13

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

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

Given numbers are 383, 130, 455, 280

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

Apply this formula for all numbers.

Step1:

LCM(383, 130) = 49790

GCD(383, 130) = ( 383 x 130 ) / 49790

= 383 / 130

= 383

Step2:

LCM(1, 455) = 455

GCD(1, 455) = ( 1 x 455 ) / 455

= 1 / 455

= 1

Step3:

LCM(1, 280) = 280

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

= 1 / 280

= 1

So, Greatest Common Divisor of 383, 130, 455, 280 is 1
