Given numbers are 462, 208, 644, 681

The list of prime factors of all numbers are

Prime factors of 462 are 2 x 3 x 7 x 11

Prime factors of 208 are 2 x 2 x 2 x 2 x 13

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 681 are 3 x 227

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

Given numbers are 462, 208, 644, 681

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

Apply this formula for all numbers.

Step1:

LCM(462, 208) = 48048

GCD(462, 208) = ( 462 x 208 ) / 48048

= 462 / 208

= 462

Step2:

LCM(2, 644) = 644

GCD(2, 644) = ( 2 x 644 ) / 644

= 2 / 644

= 2

Step3:

LCM(2, 681) = 1362

GCD(2, 681) = ( 2 x 681 ) / 1362

= 2 / 681

= 2

So, Greatest Common Divisor of 462, 208, 644, 681 is 1
