Given numbers are 643, 253, 446, 456

The list of prime factors of all numbers are

Prime factors of 643 are 643

Prime factors of 253 are 11 x 23

Prime factors of 446 are 2 x 223

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

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

Given numbers are 643, 253, 446, 456

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

Apply this formula for all numbers.

Step1:

LCM(643, 253) = 162679

GCD(643, 253) = ( 643 x 253 ) / 162679

= 643 / 253

= 643

Step2:

LCM(1, 446) = 446

GCD(1, 446) = ( 1 x 446 ) / 446

= 1 / 446

= 1

Step3:

LCM(1, 456) = 456

GCD(1, 456) = ( 1 x 456 ) / 456

= 1 / 456

= 1

So, Greatest Common Divisor of 643, 253, 446, 456 is 1
