Given numbers are 345, 407, 63, 564

The list of prime factors of all numbers are

Prime factors of 345 are 3 x 5 x 23

Prime factors of 407 are 11 x 37

Prime factors of 63 are 3 x 3 x 7

Prime factors of 564 are 2 x 2 x 3 x 47

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

Given numbers are 345, 407, 63, 564

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

Apply this formula for all numbers.

Step1:

LCM(345, 407) = 140415

GCD(345, 407) = ( 345 x 407 ) / 140415

= 345 / 407

= 345

Step2:

LCM(1, 63) = 63

GCD(1, 63) = ( 1 x 63 ) / 63

= 1 / 63

= 1

Step3:

LCM(1, 564) = 564

GCD(1, 564) = ( 1 x 564 ) / 564

= 1 / 564

= 1

So, Greatest Common Divisor of 345, 407, 63, 564 is 1
