Given numbers are 156, 280, 561, 446

The list of prime factors of all numbers are

Prime factors of 156 are 2 x 2 x 3 x 13

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

Prime factors of 561 are 3 x 11 x 17

Prime factors of 446 are 2 x 223

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

Given numbers are 156, 280, 561, 446

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

Apply this formula for all numbers.

Step1:

LCM(156, 280) = 10920

GCD(156, 280) = ( 156 x 280 ) / 10920

= 156 / 280

= 156

Step2:

LCM(4, 561) = 2244

GCD(4, 561) = ( 4 x 561 ) / 2244

= 4 / 561

= 4

Step3:

LCM(1, 446) = 446

GCD(1, 446) = ( 1 x 446 ) / 446

= 1 / 446

= 1

So, Greatest Common Divisor of 156, 280, 561, 446 is 1
