Given numbers are 402, 797, 286, 648

The list of prime factors of all numbers are

Prime factors of 402 are 2 x 3 x 67

Prime factors of 797 are 797

Prime factors of 286 are 2 x 11 x 13

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

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

Given numbers are 402, 797, 286, 648

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

Apply this formula for all numbers.

Step1:

LCM(402, 797) = 320394

GCD(402, 797) = ( 402 x 797 ) / 320394

= 402 / 797

= 402

Step2:

LCM(1, 286) = 286

GCD(1, 286) = ( 1 x 286 ) / 286

= 1 / 286

= 1

Step3:

LCM(1, 648) = 648

GCD(1, 648) = ( 1 x 648 ) / 648

= 1 / 648

= 1

So, Greatest Common Divisor of 402, 797, 286, 648 is 1
