Given numbers are 180, 405, 842, 357

The list of prime factors of all numbers are

Prime factors of 180 are 2 x 2 x 3 x 3 x 5

Prime factors of 405 are 3 x 3 x 3 x 3 x 5

Prime factors of 842 are 2 x 421

Prime factors of 357 are 3 x 7 x 17

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

Given numbers are 180, 405, 842, 357

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

Apply this formula for all numbers.

Step1:

LCM(180, 405) = 1620

GCD(180, 405) = ( 180 x 405 ) / 1620

= 180 / 405

= 180

Step2:

LCM(45, 842) = 37890

GCD(45, 842) = ( 45 x 842 ) / 37890

= 45 / 842

= 45

Step3:

LCM(1, 357) = 357

GCD(1, 357) = ( 1 x 357 ) / 357

= 1 / 357

= 1

So, Greatest Common Divisor of 180, 405, 842, 357 is 1
