Given numbers are 561, 400, 607, 458

The list of prime factors of all numbers are

Prime factors of 561 are 3 x 11 x 17

Prime factors of 400 are 2 x 2 x 2 x 2 x 5 x 5

Prime factors of 607 are 607

Prime factors of 458 are 2 x 229

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

Given numbers are 561, 400, 607, 458

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

Apply this formula for all numbers.

Step1:

LCM(561, 400) = 224400

GCD(561, 400) = ( 561 x 400 ) / 224400

= 561 / 400

= 561

Step2:

LCM(1, 607) = 607

GCD(1, 607) = ( 1 x 607 ) / 607

= 1 / 607

= 1

Step3:

LCM(1, 458) = 458

GCD(1, 458) = ( 1 x 458 ) / 458

= 1 / 458

= 1

So, Greatest Common Divisor of 561, 400, 607, 458 is 1
