Given numbers are 561, 153, 650, 485

The list of prime factors of all numbers are

Prime factors of 561 are 3 x 11 x 17

Prime factors of 153 are 3 x 3 x 17

Prime factors of 650 are 2 x 5 x 5 x 13

Prime factors of 485 are 5 x 97

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

Given numbers are 561, 153, 650, 485

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

Apply this formula for all numbers.

Step1:

LCM(561, 153) = 1683

GCD(561, 153) = ( 561 x 153 ) / 1683

= 561 / 153

= 561

Step2:

LCM(51, 650) = 33150

GCD(51, 650) = ( 51 x 650 ) / 33150

= 51 / 650

= 51

Step3:

LCM(1, 485) = 485

GCD(1, 485) = ( 1 x 485 ) / 485

= 1 / 485

= 1

So, Greatest Common Divisor of 561, 153, 650, 485 is 1
