Given numbers are 143, 183, 342, 644

The list of prime factors of all numbers are

Prime factors of 143 are 11 x 13

Prime factors of 183 are 3 x 61

Prime factors of 342 are 2 x 3 x 3 x 19

Prime factors of 644 are 2 x 2 x 7 x 23

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

Given numbers are 143, 183, 342, 644

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

Apply this formula for all numbers.

Step1:

LCM(143, 183) = 26169

GCD(143, 183) = ( 143 x 183 ) / 26169

= 143 / 183

= 143

Step2:

LCM(1, 342) = 342

GCD(1, 342) = ( 1 x 342 ) / 342

= 1 / 342

= 1

Step3:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

So, Greatest Common Divisor of 143, 183, 342, 644 is 1
