Given numbers are 383, 202, 390, 684

The list of prime factors of all numbers are

Prime factors of 383 are 383

Prime factors of 202 are 2 x 101

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

Prime factors of 684 are 2 x 2 x 3 x 3 x 19

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

Given numbers are 383, 202, 390, 684

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

Apply this formula for all numbers.

Step1:

LCM(383, 202) = 77366

GCD(383, 202) = ( 383 x 202 ) / 77366

= 383 / 202

= 383

Step2:

LCM(1, 390) = 390

GCD(1, 390) = ( 1 x 390 ) / 390

= 1 / 390

= 1

Step3:

LCM(1, 684) = 684

GCD(1, 684) = ( 1 x 684 ) / 684

= 1 / 684

= 1

So, Greatest Common Divisor of 383, 202, 390, 684 is 1
