Given numbers are 143, 555, 408, 618

The list of prime factors of all numbers are

Prime factors of 143 are 11 x 13

Prime factors of 555 are 3 x 5 x 37

Prime factors of 408 are 2 x 2 x 2 x 3 x 17

Prime factors of 618 are 2 x 3 x 103

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

Given numbers are 143, 555, 408, 618

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

Apply this formula for all numbers.

Step1:

LCM(143, 555) = 79365

GCD(143, 555) = ( 143 x 555 ) / 79365

= 143 / 555

= 143

Step2:

LCM(1, 408) = 408

GCD(1, 408) = ( 1 x 408 ) / 408

= 1 / 408

= 1

Step3:

LCM(1, 618) = 618

GCD(1, 618) = ( 1 x 618 ) / 618

= 1 / 618

= 1

So, Greatest Common Divisor of 143, 555, 408, 618 is 1
