Given numbers are 660, 395, 780, 898

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 395 are 5 x 79

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

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 660, 395, 780, 898

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

Apply this formula for all numbers.

Step1:

LCM(660, 395) = 52140

GCD(660, 395) = ( 660 x 395 ) / 52140

= 660 / 395

= 660

Step2:

LCM(5, 780) = 780

GCD(5, 780) = ( 5 x 780 ) / 780

= 5 / 780

= 5

Step3:

LCM(5, 898) = 4490

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

= 5 / 898

= 5

So, Greatest Common Divisor of 660, 395, 780, 898 is 1
