Given numbers are 660, 245, 898, 872

The list of prime factors of all numbers are

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 245 are 5 x 7 x 7

Prime factors of 898 are 2 x 449

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

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

Given numbers are 660, 245, 898, 872

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

Apply this formula for all numbers.

Step1:

LCM(660, 245) = 32340

GCD(660, 245) = ( 660 x 245 ) / 32340

= 660 / 245

= 660

Step2:

LCM(5, 898) = 4490

GCD(5, 898) = ( 5 x 898 ) / 4490

= 5 / 898

= 5

Step3:

LCM(1, 872) = 872

GCD(1, 872) = ( 1 x 872 ) / 872

= 1 / 872

= 1

So, Greatest Common Divisor of 660, 245, 898, 872 is 1
