Given numbers are 662, 450, 390, 663

The list of prime factors of all numbers are

Prime factors of 662 are 2 x 331

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

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 663 are 3 x 13 x 17

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

Given numbers are 662, 450, 390, 663

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

Apply this formula for all numbers.

Step1:

LCM(662, 450) = 148950

GCD(662, 450) = ( 662 x 450 ) / 148950

= 662 / 450

= 662

Step2:

LCM(2, 390) = 390

GCD(2, 390) = ( 2 x 390 ) / 390

= 2 / 390

= 2

Step3:

LCM(2, 663) = 1326

GCD(2, 663) = ( 2 x 663 ) / 1326

= 2 / 663

= 2

So, Greatest Common Divisor of 662, 450, 390, 663 is 1
