Given numbers are 143, 305, 368, 145

The list of prime factors of all numbers are

Prime factors of 143 are 11 x 13

Prime factors of 305 are 5 x 61

Prime factors of 368 are 2 x 2 x 2 x 2 x 23

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 143, 305, 368, 145

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

Apply this formula for all numbers.

Step1:

LCM(143, 305) = 43615

GCD(143, 305) = ( 143 x 305 ) / 43615

= 143 / 305

= 143

Step2:

LCM(1, 368) = 368

GCD(1, 368) = ( 1 x 368 ) / 368

= 1 / 368

= 1

Step3:

LCM(1, 145) = 145

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

= 1 / 145

= 1

So, Greatest Common Divisor of 143, 305, 368, 145 is 1
