Given numbers are 611, 780, 544, 491

The list of prime factors of all numbers are

Prime factors of 611 are 13 x 47

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

Prime factors of 544 are 2 x 2 x 2 x 2 x 2 x 17

Prime factors of 491 are 491

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

Given numbers are 611, 780, 544, 491

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

Apply this formula for all numbers.

Step1:

LCM(611, 780) = 36660

GCD(611, 780) = ( 611 x 780 ) / 36660

= 611 / 780

= 611

Step2:

LCM(13, 544) = 7072

GCD(13, 544) = ( 13 x 544 ) / 7072

= 13 / 544

= 13

Step3:

LCM(1, 491) = 491

GCD(1, 491) = ( 1 x 491 ) / 491

= 1 / 491

= 1

So, Greatest Common Divisor of 611, 780, 544, 491 is 1
