Given numbers are 561, 170, 495, 158

The list of prime factors of all numbers are

Prime factors of 561 are 3 x 11 x 17

Prime factors of 170 are 2 x 5 x 17

Prime factors of 495 are 3 x 3 x 5 x 11

Prime factors of 158 are 2 x 79

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

Given numbers are 561, 170, 495, 158

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

Apply this formula for all numbers.

Step1:

LCM(561, 170) = 5610

GCD(561, 170) = ( 561 x 170 ) / 5610

= 561 / 170

= 561

Step2:

LCM(17, 495) = 8415

GCD(17, 495) = ( 17 x 495 ) / 8415

= 17 / 495

= 17

Step3:

LCM(1, 158) = 158

GCD(1, 158) = ( 1 x 158 ) / 158

= 1 / 158

= 1

So, Greatest Common Divisor of 561, 170, 495, 158 is 1
