Given numbers are 872, 780, 318, 245

The list of prime factors of all numbers are

Prime factors of 872 are 2 x 2 x 2 x 109

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

Prime factors of 318 are 2 x 3 x 53

Prime factors of 245 are 5 x 7 x 7

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

Given numbers are 872, 780, 318, 245

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

Apply this formula for all numbers.

Step1:

LCM(872, 780) = 170040

GCD(872, 780) = ( 872 x 780 ) / 170040

= 872 / 780

= 872

Step2:

LCM(4, 318) = 636

GCD(4, 318) = ( 4 x 318 ) / 636

= 4 / 318

= 4

Step3:

LCM(2, 245) = 490

GCD(2, 245) = ( 2 x 245 ) / 490

= 2 / 245

= 2

So, Greatest Common Divisor of 872, 780, 318, 245 is 1
