Given numbers are 561, 451, 858, 751

The list of prime factors of all numbers are

Prime factors of 561 are 3 x 11 x 17

Prime factors of 451 are 11 x 41

Prime factors of 858 are 2 x 3 x 11 x 13

Prime factors of 751 are 751

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

Given numbers are 561, 451, 858, 751

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

Apply this formula for all numbers.

Step1:

LCM(561, 451) = 23001

GCD(561, 451) = ( 561 x 451 ) / 23001

= 561 / 451

= 561

Step2:

LCM(11, 858) = 858

GCD(11, 858) = ( 11 x 858 ) / 858

= 11 / 858

= 11

Step3:

LCM(11, 751) = 8261

GCD(11, 751) = ( 11 x 751 ) / 8261

= 11 / 751

= 11

So, Greatest Common Divisor of 561, 451, 858, 751 is 1
