Given numbers are 430, 519, 780, 455

The list of prime factors of all numbers are

Prime factors of 430 are 2 x 5 x 43

Prime factors of 519 are 3 x 173

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 455 are 5 x 7 x 13

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

Given numbers are 430, 519, 780, 455

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

Apply this formula for all numbers.

Step1:

LCM(430, 519) = 223170

GCD(430, 519) = ( 430 x 519 ) / 223170

= 430 / 519

= 430

Step2:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

Step3:

LCM(1, 455) = 455

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

= 1 / 455

= 1

So, Greatest Common Divisor of 430, 519, 780, 455 is 1
