Given numbers are 780, 765, 209, 547

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 765 are 3 x 3 x 5 x 17

Prime factors of 209 are 11 x 19

Prime factors of 547 are 547

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

Given numbers are 780, 765, 209, 547

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

Apply this formula for all numbers.

Step1:

LCM(780, 765) = 39780

GCD(780, 765) = ( 780 x 765 ) / 39780

= 780 / 765

= 780

Step2:

LCM(15, 209) = 3135

GCD(15, 209) = ( 15 x 209 ) / 3135

= 15 / 209

= 15

Step3:

LCM(1, 547) = 547

GCD(1, 547) = ( 1 x 547 ) / 547

= 1 / 547

= 1

So, Greatest Common Divisor of 780, 765, 209, 547 is 1
