Given numbers are 399, 656, 782, 450

The list of prime factors of all numbers are

Prime factors of 399 are 3 x 7 x 19

Prime factors of 656 are 2 x 2 x 2 x 2 x 41

Prime factors of 782 are 2 x 17 x 23

Prime factors of 450 are 2 x 3 x 3 x 5 x 5

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

Given numbers are 399, 656, 782, 450

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

Apply this formula for all numbers.

Step1:

LCM(399, 656) = 261744

GCD(399, 656) = ( 399 x 656 ) / 261744

= 399 / 656

= 399

Step2:

LCM(1, 782) = 782

GCD(1, 782) = ( 1 x 782 ) / 782

= 1 / 782

= 1

Step3:

LCM(1, 450) = 450

GCD(1, 450) = ( 1 x 450 ) / 450

= 1 / 450

= 1

So, Greatest Common Divisor of 399, 656, 782, 450 is 1
