Given numbers are 143, 511, 438, 415

The list of prime factors of all numbers are

Prime factors of 143 are 11 x 13

Prime factors of 511 are 7 x 73

Prime factors of 438 are 2 x 3 x 73

Prime factors of 415 are 5 x 83

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

Given numbers are 143, 511, 438, 415

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

Apply this formula for all numbers.

Step1:

LCM(143, 511) = 73073

GCD(143, 511) = ( 143 x 511 ) / 73073

= 143 / 511

= 143

Step2:

LCM(1, 438) = 438

GCD(1, 438) = ( 1 x 438 ) / 438

= 1 / 438

= 1

Step3:

LCM(1, 415) = 415

GCD(1, 415) = ( 1 x 415 ) / 415

= 1 / 415

= 1

So, Greatest Common Divisor of 143, 511, 438, 415 is 1
