Given numbers are 561, 641, 840, 466

The list of prime factors of all numbers are

Prime factors of 561 are 3 x 11 x 17

Prime factors of 641 are 641

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 466 are 2 x 233

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

Given numbers are 561, 641, 840, 466

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

Apply this formula for all numbers.

Step1:

LCM(561, 641) = 359601

GCD(561, 641) = ( 561 x 641 ) / 359601

= 561 / 641

= 561

Step2:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

Step3:

LCM(1, 466) = 466

GCD(1, 466) = ( 1 x 466 ) / 466

= 1 / 466

= 1

So, Greatest Common Divisor of 561, 641, 840, 466 is 1
