Given numbers are 780, 143, 489, 190

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 143 are 11 x 13

Prime factors of 489 are 3 x 163

Prime factors of 190 are 2 x 5 x 19

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

Given numbers are 780, 143, 489, 190

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

Apply this formula for all numbers.

Step1:

LCM(780, 143) = 8580

GCD(780, 143) = ( 780 x 143 ) / 8580

= 780 / 143

= 780

Step2:

LCM(13, 489) = 6357

GCD(13, 489) = ( 13 x 489 ) / 6357

= 13 / 489

= 13

Step3:

LCM(1, 190) = 190

GCD(1, 190) = ( 1 x 190 ) / 190

= 1 / 190

= 1

So, Greatest Common Divisor of 780, 143, 489, 190 is 1
