Given numbers are 143, 851, 642, 303

The list of prime factors of all numbers are

Prime factors of 143 are 11 x 13

Prime factors of 851 are 23 x 37

Prime factors of 642 are 2 x 3 x 107

Prime factors of 303 are 3 x 101

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

Given numbers are 143, 851, 642, 303

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

Apply this formula for all numbers.

Step1:

LCM(143, 851) = 121693

GCD(143, 851) = ( 143 x 851 ) / 121693

= 143 / 851

= 143

Step2:

LCM(1, 642) = 642

GCD(1, 642) = ( 1 x 642 ) / 642

= 1 / 642

= 1

Step3:

LCM(1, 303) = 303

GCD(1, 303) = ( 1 x 303 ) / 303

= 1 / 303

= 1

So, Greatest Common Divisor of 143, 851, 642, 303 is 1
