Given numbers are 142, 570, 721, 841

The list of prime factors of all numbers are

Prime factors of 142 are 2 x 71

Prime factors of 570 are 2 x 3 x 5 x 19

Prime factors of 721 are 7 x 103

Prime factors of 841 are 29 x 29

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

Given numbers are 142, 570, 721, 841

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

Apply this formula for all numbers.

Step1:

LCM(142, 570) = 40470

GCD(142, 570) = ( 142 x 570 ) / 40470

= 142 / 570

= 142

Step2:

LCM(2, 721) = 1442

GCD(2, 721) = ( 2 x 721 ) / 1442

= 2 / 721

= 2

Step3:

LCM(1, 841) = 841

GCD(1, 841) = ( 1 x 841 ) / 841

= 1 / 841

= 1

So, Greatest Common Divisor of 142, 570, 721, 841 is 1
