Given numbers are 409, 312, 554, 565

The list of prime factors of all numbers are

Prime factors of 409 are 409

Prime factors of 312 are 2 x 2 x 2 x 3 x 13

Prime factors of 554 are 2 x 277

Prime factors of 565 are 5 x 113

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

Given numbers are 409, 312, 554, 565

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

Apply this formula for all numbers.

Step1:

LCM(409, 312) = 127608

GCD(409, 312) = ( 409 x 312 ) / 127608

= 409 / 312

= 409

Step2:

LCM(1, 554) = 554

GCD(1, 554) = ( 1 x 554 ) / 554

= 1 / 554

= 1

Step3:

LCM(1, 565) = 565

GCD(1, 565) = ( 1 x 565 ) / 565

= 1 / 565

= 1

So, Greatest Common Divisor of 409, 312, 554, 565 is 1
