The list of prime factors of all numbers are

Prime factors of 561 are 3 x 11 x 17

Prime factors of 860 are 2 x 2 x 5 x 43

Prime factors of 453 are 3 x 151

Prime factors of 755 are 5 x 151

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

Given numbers are 561, 860, 453, 755

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

Apply this formula for all numbers.

Step1:

LCM(561, 860) = 482460

GCD(561, 860) = ( 561 x 860 ) / 482460

= 561 / 860

= 561

Step2:

LCM(1, 453) = 453

GCD(1, 453) = ( 1 x 453 ) / 453

= 1 / 453

= 1

Step3:

LCM(1, 755) = 755

GCD(1, 755) = ( 1 x 755 ) / 755

= 1 / 755

= 1

So, Greatest Common Divisor of 561, 860, 453, 755 is 1
