Given numbers are 142, 170, 869, 454

The list of prime factors of all numbers are

Prime factors of 142 are 2 x 71

Prime factors of 170 are 2 x 5 x 17

Prime factors of 869 are 11 x 79

Prime factors of 454 are 2 x 227

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

Given numbers are 142, 170, 869, 454

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

Apply this formula for all numbers.

Step1:

LCM(142, 170) = 12070

GCD(142, 170) = ( 142 x 170 ) / 12070

= 142 / 170

= 142

Step2:

LCM(2, 869) = 1738

GCD(2, 869) = ( 2 x 869 ) / 1738

= 2 / 869

= 2

Step3:

LCM(1, 454) = 454

GCD(1, 454) = ( 1 x 454 ) / 454

= 1 / 454

= 1

So, Greatest Common Divisor of 142, 170, 869, 454 is 1
