Given numbers are 145, 220, 513, 798

The list of prime factors of all numbers are

Prime factors of 145 are 5 x 29

Prime factors of 220 are 2 x 2 x 5 x 11

Prime factors of 513 are 3 x 3 x 3 x 19

Prime factors of 798 are 2 x 3 x 7 x 19

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

Given numbers are 145, 220, 513, 798

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

Apply this formula for all numbers.

Step1:

LCM(145, 220) = 6380

GCD(145, 220) = ( 145 x 220 ) / 6380

= 145 / 220

= 145

Step2:

LCM(5, 513) = 2565

GCD(5, 513) = ( 5 x 513 ) / 2565

= 5 / 513

= 5

Step3:

LCM(1, 798) = 798

GCD(1, 798) = ( 1 x 798 ) / 798

= 1 / 798

= 1

So, Greatest Common Divisor of 145, 220, 513, 798 is 1
