Given numbers are 363, 646, 402, 680

The list of prime factors of all numbers are

Prime factors of 363 are 3 x 11 x 11

Prime factors of 646 are 2 x 17 x 19

Prime factors of 402 are 2 x 3 x 67

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

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

Given numbers are 363, 646, 402, 680

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

Apply this formula for all numbers.

Step1:

LCM(363, 646) = 234498

GCD(363, 646) = ( 363 x 646 ) / 234498

= 363 / 646

= 363

Step2:

LCM(1, 402) = 402

GCD(1, 402) = ( 1 x 402 ) / 402

= 1 / 402

= 1

Step3:

LCM(1, 680) = 680

GCD(1, 680) = ( 1 x 680 ) / 680

= 1 / 680

= 1

So, Greatest Common Divisor of 363, 646, 402, 680 is 1
