Given numbers are 456, 661, 828, 439

The list of prime factors of all numbers are

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

Prime factors of 661 are 661

Prime factors of 828 are 2 x 2 x 3 x 3 x 23

Prime factors of 439 are 439

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

Given numbers are 456, 661, 828, 439

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

Apply this formula for all numbers.

Step1:

LCM(456, 661) = 301416

GCD(456, 661) = ( 456 x 661 ) / 301416

= 456 / 661

= 456

Step2:

LCM(1, 828) = 828

GCD(1, 828) = ( 1 x 828 ) / 828

= 1 / 828

= 1

Step3:

LCM(1, 439) = 439

GCD(1, 439) = ( 1 x 439 ) / 439

= 1 / 439

= 1

So, Greatest Common Divisor of 456, 661, 828, 439 is 1
