Given numbers are 686, 805, 300, 647

The list of prime factors of all numbers are

Prime factors of 686 are 2 x 7 x 7 x 7

Prime factors of 805 are 5 x 7 x 23

Prime factors of 300 are 2 x 2 x 3 x 5 x 5

Prime factors of 647 are 647

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

Given numbers are 686, 805, 300, 647

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

Apply this formula for all numbers.

Step1:

LCM(686, 805) = 78890

GCD(686, 805) = ( 686 x 805 ) / 78890

= 686 / 805

= 686

Step2:

LCM(7, 300) = 2100

GCD(7, 300) = ( 7 x 300 ) / 2100

= 7 / 300

= 7

Step3:

LCM(1, 647) = 647

GCD(1, 647) = ( 1 x 647 ) / 647

= 1 / 647

= 1

So, Greatest Common Divisor of 686, 805, 300, 647 is 1
