Given numbers are 574, 181, 644, 865

The list of prime factors of all numbers are

Prime factors of 574 are 2 x 7 x 41

Prime factors of 181 are 181

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 865 are 5 x 173

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

Given numbers are 574, 181, 644, 865

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

Apply this formula for all numbers.

Step1:

LCM(574, 181) = 103894

GCD(574, 181) = ( 574 x 181 ) / 103894

= 574 / 181

= 574

Step2:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

Step3:

LCM(1, 865) = 865

GCD(1, 865) = ( 1 x 865 ) / 865

= 1 / 865

= 1

So, Greatest Common Divisor of 574, 181, 644, 865 is 1
