Given numbers are 364, 620, 390, 663

The list of prime factors of all numbers are

Prime factors of 364 are 2 x 2 x 7 x 13

Prime factors of 620 are 2 x 2 x 5 x 31

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 364, 620, 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(364, 620) = 56420

GCD(364, 620) = ( 364 x 620 ) / 56420

= 364 / 620

= 364

Step2:

LCM(4, 390) = 780

GCD(4, 390) = ( 4 x 390 ) / 780

= 4 / 390

= 4

Step3:

LCM(2, 663) = 1326

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

= 2 / 663

= 2

So, Greatest Common Divisor of 364, 620, 390, 663 is 1
