Given numbers are 780, 729, 911, 540

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 729 are 3 x 3 x 3 x 3 x 3 x 3

Prime factors of 911 are 911

Prime factors of 540 are 2 x 2 x 3 x 3 x 3 x 5

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

Given numbers are 780, 729, 911, 540

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

Apply this formula for all numbers.

Step1:

LCM(780, 729) = 189540

GCD(780, 729) = ( 780 x 729 ) / 189540

= 780 / 729

= 780

Step2:

LCM(3, 911) = 2733

GCD(3, 911) = ( 3 x 911 ) / 2733

= 3 / 911

= 3

Step3:

LCM(1, 540) = 540

GCD(1, 540) = ( 1 x 540 ) / 540

= 1 / 540

= 1

So, Greatest Common Divisor of 780, 729, 911, 540 is 1
