Given numbers are 834, 623, 155, 561

The list of prime factors of all numbers are

Prime factors of 834 are 2 x 3 x 139

Prime factors of 623 are 7 x 89

Prime factors of 155 are 5 x 31

Prime factors of 561 are 3 x 11 x 17

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

Given numbers are 834, 623, 155, 561

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

Apply this formula for all numbers.

Step1:

LCM(834, 623) = 519582

GCD(834, 623) = ( 834 x 623 ) / 519582

= 834 / 623

= 834

Step2:

LCM(1, 155) = 155

GCD(1, 155) = ( 1 x 155 ) / 155

= 1 / 155

= 1

Step3:

LCM(1, 561) = 561

GCD(1, 561) = ( 1 x 561 ) / 561

= 1 / 561

= 1

So, Greatest Common Divisor of 834, 623, 155, 561 is 1
