Given numbers are 545, 456, 407

The list of prime factors of all numbers are

Prime factors of 545 are 5 x 109

Prime factors of 456 are 2 x 2 x 2 x 3 x 19

Prime factors of 407 are 11 x 37

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

Given numbers are 545, 456, 407

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

Apply this formula for all numbers.

Step1:

LCM(545, 456) = 248520

GCD(545, 456) = ( 545 x 456 ) / 248520

= 545 / 456

= 545

Step2:

LCM(1, 407) = 407

GCD(1, 407) = ( 1 x 407 ) / 407

= 1 / 407

= 1

So, Greatest Common Divisor of 545, 456, 407 is 1
