Given numbers are 780, 308, 437, 491

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 308 are 2 x 2 x 7 x 11

Prime factors of 437 are 19 x 23

Prime factors of 491 are 491

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

Given numbers are 780, 308, 437, 491

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

Apply this formula for all numbers.

Step1:

LCM(780, 308) = 60060

GCD(780, 308) = ( 780 x 308 ) / 60060

= 780 / 308

= 780

Step2:

LCM(4, 437) = 1748

GCD(4, 437) = ( 4 x 437 ) / 1748

= 4 / 437

= 4

Step3:

LCM(1, 491) = 491

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

= 1 / 491

= 1

So, Greatest Common Divisor of 780, 308, 437, 491 is 1
