Given numbers are 780, 585, 764, 898

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 585 are 3 x 3 x 5 x 13

Prime factors of 764 are 2 x 2 x 191

Prime factors of 898 are 2 x 449

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

Given numbers are 780, 585, 764, 898

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

Apply this formula for all numbers.

Step1:

LCM(780, 585) = 2340

GCD(780, 585) = ( 780 x 585 ) / 2340

= 780 / 585

= 780

Step2:

LCM(195, 764) = 148980

GCD(195, 764) = ( 195 x 764 ) / 148980

= 195 / 764

= 195

Step3:

LCM(1, 898) = 898

GCD(1, 898) = ( 1 x 898 ) / 898

= 1 / 898

= 1

So, Greatest Common Divisor of 780, 585, 764, 898 is 1
