Given numbers are 813, 145, 340, 553

The list of prime factors of all numbers are

Prime factors of 813 are 3 x 271

Prime factors of 145 are 5 x 29

Prime factors of 340 are 2 x 2 x 5 x 17

Prime factors of 553 are 7 x 79

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

Given numbers are 813, 145, 340, 553

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

Apply this formula for all numbers.

Step1:

LCM(813, 145) = 117885

GCD(813, 145) = ( 813 x 145 ) / 117885

= 813 / 145

= 813

Step2:

LCM(1, 340) = 340

GCD(1, 340) = ( 1 x 340 ) / 340

= 1 / 340

= 1

Step3:

LCM(1, 553) = 553

GCD(1, 553) = ( 1 x 553 ) / 553

= 1 / 553

= 1

So, Greatest Common Divisor of 813, 145, 340, 553 is 1
