Given numbers are 745, 515, 198, 145

The list of prime factors of all numbers are

Prime factors of 745 are 5 x 149

Prime factors of 515 are 5 x 103

Prime factors of 198 are 2 x 3 x 3 x 11

Prime factors of 145 are 5 x 29

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

Given numbers are 745, 515, 198, 145

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

Apply this formula for all numbers.

Step1:

LCM(745, 515) = 76735

GCD(745, 515) = ( 745 x 515 ) / 76735

= 745 / 515

= 745

Step2:

LCM(5, 198) = 990

GCD(5, 198) = ( 5 x 198 ) / 990

= 5 / 198

= 5

Step3:

LCM(1, 145) = 145

GCD(1, 145) = ( 1 x 145 ) / 145

= 1 / 145

= 1

So, Greatest Common Divisor of 745, 515, 198, 145 is 1
