Given numbers are 780, 125, 430, 554

The list of prime factors of all numbers are

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

Prime factors of 125 are 5 x 5 x 5

Prime factors of 430 are 2 x 5 x 43

Prime factors of 554 are 2 x 277

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

Given numbers are 780, 125, 430, 554

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

Apply this formula for all numbers.

Step1:

LCM(780, 125) = 19500

GCD(780, 125) = ( 780 x 125 ) / 19500

= 780 / 125

= 780

Step2:

LCM(5, 430) = 430

GCD(5, 430) = ( 5 x 430 ) / 430

= 5 / 430

= 5

Step3:

LCM(5, 554) = 2770

GCD(5, 554) = ( 5 x 554 ) / 2770

= 5 / 554

= 5

So, Greatest Common Divisor of 780, 125, 430, 554 is 1
