Given numbers are 560, 780, 767, 491

The list of prime factors of all numbers are

Prime factors of 560 are 2 x 2 x 2 x 2 x 5 x 7

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

Prime factors of 767 are 13 x 59

Prime factors of 491 are 491

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

Given numbers are 560, 780, 767, 491

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

Apply this formula for all numbers.

Step1:

LCM(560, 780) = 21840

GCD(560, 780) = ( 560 x 780 ) / 21840

= 560 / 780

= 560

Step2:

LCM(20, 767) = 15340

GCD(20, 767) = ( 20 x 767 ) / 15340

= 20 / 767

= 20

Step3:

LCM(1, 491) = 491

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

= 1 / 491

= 1

So, Greatest Common Divisor of 560, 780, 767, 491 is 1
